Find the measure of angle 7 Measure of angle 7= 2x + 15 Measure of angle 8= 3x

1 answer:

7 0

Assuming ∠6 and angle ∠8 are vertical angles, then
m∠6 = m∠8 
m∠6 + m∠7 = m∠7 + m∠8 = 180 

2x + 15 + 3x = 180 
5x = 165 
x = 33 

m∠7 = 2(33)+15 = 81 
m∠8 = 3(33) = 99 

m∠6 = m∠8 = 99

Sholpan [36]

We are give the equation of the perimeter of the triangle as follows:
2a + b = 15.7
where b represents the base.

Now, if we want to calculate the length of the base, all we have to do is isolate the b in one side of the equation as follows:
b = 15.7 - 2a

We know that a = 6.3 cm, therefore, the length of the base can be calculated as follows:
b = 15.7 - 2(6.3) = 3.1 cm
