-3(5t+2)
.....................................................................................................................
Step-by-step explanation:
- (8x-38°)=90° {because of being vertically opposite angles}
- 8x-38°=90°
- 8x=90°-38°
- 8x=52°
- x=52°/8
- x=6.5°
- z°+90°=180° {being linear pair}
- z°=180°-90°
- z°=90°
Answer:
35
Step-by-step explanation:
In this shape we have to use the formula: A= 1/2xbxh
So we use this formula. 1/2 X (5 X 14)= 35
