The measure of ∠dab is 70 the measure of ∠dae is 10 the measure of ∠eba is 60 the measure of ∠ebd is 20 line ef is parallel to ab find the measure of ∠ade

the answer is b.

step-by-step explanation:

identity property is where 0+whatever number=whatever number. basically 0+ a number.

logv3(x+2)=1

rewrite in exponential form:

logb(x) = y is equal to b^y =x

b = 3, y = 1

now solve for x:

3^1 = x+2)

x = 3-2

x = 1
