Answer:
X = 40°
Step-by-step explanation:
The triangle on the left is an Isosceles triangle which means it has 2 equal sides. So, to find the third angle, u have to minus 180 and both the base angles.
180° - 35° - 35°
= 110°
Then, minus 180 with the right triangle base bcs a straight line is 180°.
So,
180 - 110
= 70°
Now u got the right triangle base which is also an isosceles triangle so both angles are 70°
Now to find the third angle, minus 180 to both the base angles
180 - 70 - 70
= 40°
And that's your answer.
