I think you have not asked the question correctly.
I guess you meant that the sides of the triangle are 3, 4 and 5. Similarly you have given no indication of which angle is opposite which side.
A 3, 4, 5 triangle is a right angle triangle (5 is the hypotenuse).
Thus depending where angle B is, its sine will be:
The angles are: 40, 60 and 80 degrees
a quadrilateral can have from 0 to 4 right angles. But it can't have exactly three right angles. The interior angles of a quadrilateral sum to 360 degrees. If it had three right angles and x were the measure of the fourth angle: 3*90+x=360 x=360-270=90 So if it has three right angles, the fourth angle would be a right angle as well.
If it's a quadrilateral then the other 3 angles must add up to 335 degrees because a 4 sided quadrilateral contains 360 degrees
Opposite angles of a parallelogram are equal, and adjacent angles are supplementary. Let one angle be θ, then the adjacent angle is 4θ + 50° → θ + 4θ + 50° = 180° → 5θ = 130° → θ = 26° → The two adjacent angles are 26° and 154°. → The angles of the parallelogram are 26°, 154°, 26°, 154°.
it equals 4
No. If the angles are in the ratio 3:4:5, the sides will be in the ratio sin(3):sin(4):sin(5) - NOT in the ratio 3:4:5.
Without a visual or more information, I'm guessing that the picture is of angles 1 and 2 that are consecutive (share an angle side) and a separate picture of consecutive angles 3 and 4. With that said: 1) angle 2 congruent to angle 3................1) given 2) angle 1 is supplementary to angle 2....2) If angles are next to each other --> supps angle 3 is supplementary to angle 4 3) angle 1 congruent angle 4..............3) If supps to congruents angles ---> congruent

Actually, It is this. Question: Angle 1 and 4 are called ___ angles? Answer: Supplementary
4
Say angle 1 is 40 which means that if angle 3 is congruent then angle 3 is also 40 by definition of vertical angles. That would make angle 2 equal to 140 by definition of a linear pair and so angle 4 is congruent by vertical angles.
you cannot make a regular shape which has 3 right angles only, you will always end up with 4 right angles
no because simply the triangle means 3 angles.(tri - 3) so you make 3 angle out of lets say 4 angles no because a triangle has to be 3 ANGLES,
You can show that two lines cut by a transversal are parallel in a number of ways. (1) Show that the consecutive interior angles are supplementary. Let's say your lines are arranged like this (ignore the periods, they're just there so the spacing is right): ......................1 | 2 --------------------|----------------------- .......................8| 3 .........................| ......................7 | 4 --------------------|----------------------- ......................6 | 5 If the lines are parallel, the measures of all the consecutive interior angles should be supplementary. The following should be true: Angle 8 + Angle 3 = 180 degrees Angle 3 + Angle 4 = 180 degrees Angle 4 + Angle 7 = 180 degrees and Angle 7 + Angle 8 = 180 degrees (2) You can also prove that the lines are parallel by showing that the corresponding angles are congruent. Using the line arrangement above, prove any of the following to be true: Angle 1 = Angle 7 Angle 2 = Angle 4 Angle 3 = Angle 5 or Angle 8 = Angle 6 (3) Finally, you can use alternate angles (either interior or exterior). To use alternate interior angles, prove that: Angle 3 = Angle 7 or Angle 4 = Angle 8 To use alternate exterior angles, prove that: Angle 1 = Angle 5 or Angle 2 = Angle 6 Well, there you have it! Best of luck!
Quadrilaterals are polygons having four sides. Quadrilaterals may have 1, 2, or 4 right angles. It is impossible for a quadrilateral to have exactly 3 right angles because the fourth angle would also be a right angle.
All triangles have 3 sides and 3 interior angles that add up to 180 degrees and they are classed as follows:- 1 Scalene triangle has 3 acute angles of different sizes 2 Right angle triangle has a 90 degree angle and 2 acute angles 3 Obtuse triangle has an obtuse angle and 2 acute angles 4 Isosceles triangle has 2 equal angles plus another angle 5 Equilateral triangle has 3 equal 60 degee angles
