Round off the decimals to a sensible number.
So 3.7 would be 4 and 10.2 would be 10.
In this case, it would be (2 × 4 + 8) × 10 which is 160.
Answer:
Step-by-step explanation:
area becomes 2²=4 times.
(x + 9) (x + 34)
9 * 34 = 306
9 + 34 = 43
Step-by-step explanation:
b + 81° = 117° { exterior angle of a triangle is equal to the sum of two opposite interior angles }
b = 117° - 81°
b = 36°
for no. 14
The angles that are congruent to < 1 are < 4 and < 8.
