Answer:
x = 40
Step-by-step explanation:
The sum of the 3 angles in a triangle = 180°
Consider the triangle on the left and calculate the third angle
Subtract the sum of the 2 angles from 180
third angle = 180° - (75 + 50)° = 180° - 125° = 55°
Consider the triangle on the right
The third angle = 55° ( vertical angles )
Subtract the sum of the 2 angles from 180
x = 180 - (55 + 85) = 180 - 140 = 40

Answer:
∠ 5 = 133°
Step-by-step explanation:
∠ 1 and ∠ 2 are adjacent and supplementary, thus
∠ 1 = 180° - 47° = 133°
∠ 1 and ∠ 5 are corresponding and congruent, thus
∠ 5 = ∠ 1 = 133°
Answer:
31.5
Step-by-step explanation:
The area of a triangle is 1/2 * b * h
so base times height times one half
