Please answer correctly

x = .3

Step-by-step explanation:

for ∠H we are given its opposite side length and need to find its adjacent side length

when dealing with opposite and adjacent we use tangent

recall that tan = opposite over adjacent

we now solve for x

step 1: multiply each side by x

step 2: divide each side by tan(84)

finally we round to the nearest tenth of a foot and get that x = .3

angle addition postulate

2x=56

step-by-step explanation:

m∠a is 90°

m∠b is 40°
