B = 3A : C = 0.9 x 6A
Therefore 180 = A + B + C = A + 3A + 5.4A = 9.4A : A = 180 ÷ 9.4 = 19.15° (2dp)
Then B = 57.45° and C = 103.40°

What are the properties of a acute angled triangle?
acute angle is an angle less that 90%
In triangle ABC angle B is 5 times angle A and angle C is 8 less than 4 times angle A what is the size of angle A?
B = 5A C = 4A - 8 The sum of the angles of a triangle = 180° A + B + C = 180 A + 5A + (4A - 8) = 180 10A = 188 A = 18.8° (and therefore B = 94° and C = 67.2°)
How is an acute triangle different from both an obtuse triangle and a right triangle?
An acute triangle has no angle of 90 degrees or more. A right triangle has one angle of 90 degrees; the other two are less than 90 degrees. An obtuse triangle has one angle between 90° and 180°; the other two are less than 90°.
What degree angle is an acute triangle?
An acute angle is any angle less than 90 degrees.
A right angle triangle has one angle of 90?
Yes.The definition of every triangle-Right triangle---A triangle that has one right angle(90 degrees).-Obtuse triangle---A triangle that has one obtuse angle(greater than 90 degrees).-Acute triangle---A triangle that has all acute angles(less than 90 degrees).
In triangle ABC angle B is three times angle A and angle angle C is one degree less than six times angle A find the angles?
A = 18.1 degrees B = 54.3 degrees C = 107.6 degrees
Which type of triangle has three angles with measures less than 90°?
A triangle which measures less than 90%
In triangle DEF angle E is 3 times angle D and angle F is 9 less than angle E what is the measure of each angle?
D=27 E=81 F=72
What is acute angle and isoseles angle?
acute angle is an angle that is less that 90 degrees. An isosceles triangle is a triangle that has 2 equal sides and 2 equal angles.
In triangle ABC angle B is 5 times angle A and angle C is 8 less than 4 times angle A what is the size of angle A?
B = 5A C = 4A - 8 The sum of the angles of a triangle = 180° A + B + C = 180 A + 5A + (4A - 8) = 180 10A = 188 A = 18.8° (and therefore B = 94° and C = 67.2°)
What are the properties of a acute angled triangle?
acute angle is an angle less that 90%
A triangle with all angles less than a right angle?
An acute triangle is a triangle with all angles smaller than a 90 degree right angle.
How is an acute triangle different from both an obtuse triangle and a right triangle?
An acute triangle has no angle of 90 degrees or more. A right triangle has one angle of 90 degrees; the other two are less than 90 degrees. An obtuse triangle has one angle between 90° and 180°; the other two are less than 90°.
What degree angle is an acute triangle?
An acute angle is any angle less than 90 degrees.
In a triangle abc angle b is 4 times angle a and angle c is 9 degrees less than 5 times angle a the size of a is?
a = a b = 4a c = 5a-9 a+4a+5a-9 = 180 10a = 189 a = 18.9 degrees
How would you use angle in a sentence?
A triangle has one less angle than a square.
A right angle triangle has one angle of 90?
Yes.The definition of every triangle-Right triangle---A triangle that has one right angle(90 degrees).-Obtuse triangle---A triangle that has one obtuse angle(greater than 90 degrees).-Acute triangle---A triangle that has all acute angles(less than 90 degrees).
