Answer:
x=−6±3√5
Step-by-step explanation:
Split it into 7 triangles. Half-base of each is 2 so the distance of center to the midpoint of the base is (Pythagoras) square root of (4.62 - 22) = 4.162 triangle is this times 2, and with 7 triangles multiply also by 7 to get an approximate area of 58 sq in.
Answer:
adjacent and supplementary
Step-by-step explanation:
∠ 1 and ∠ 2 are next to each other, that is adjacent.
∠ 1 and ∠ 2 form a straight angle and are supplementary.
It’s really simple 2+6=7 7\10
9.9=9×9=81 and you have to multiply
