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 are the properties of a acute angled triangle?
acute angle is an angle less that 90%
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°)
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.
What degree angle is an acute triangle?
An acute angle is any angle less than 90 degrees.
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°.
How would you use angle in a sentence?
A triangle has one less angle than a square.
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
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).
