Question

9. Find the measures of CBA and side BC in the
adjoining right triangle.

please answer in full explanation​

Answer 1

Answer:

x=35, y=10

Step-by-step explanation:

sum of the angles in a triangle = 180-90-55=35

by Pythagoras theorem

y^2=8^2+6^2

y^2=64+36=100

y=10

Answer 2

Step-by-step explanation:

Angle sum of triangle=180°

So,

55°+right angle+angle CBA=180°

55°+90°+angle CBA=180°

145°+angle CBA=180°

angle CBA=180°-145°

angle CBA=35°

8²+6²=BC² (By Pythagoras theorem)

64+36=BC²

100=BC²

10=BC

So,

angle CBA=35°

BC=10 cm
