How find the measure of angle A. Start by finding its tangent. tan Aequals=StartFraction side opposite Over side adjacent EndFraction side opposite side adjacent equals=StartFraction 73.7 Over 39.4 EndFraction 73.7 39.4 Now use a calculator to find the inverse tangent of StartFraction 73.7 Over 39.4 EndFraction 73.7 39.4. tan Aequals=StartFraction 73.7 Over 39.4 EndFraction 73.7 39.4 Aequals=61degrees° 50' (rounded).

answer: r there any options?

step-by-step explanation:

y= 2x+7

changed to y= 5x +7

as slope is increased from 2 to 5

therefore it would be less steeper

so, option d) is correct

d. corresponding side lengths in similar triangles are proportional in length.

step-by-step explanation:

answer: -10

step-by-step explanation:

s(t) = 1 - 10t

s(x) = 1 - 10x

s(x + h) = 1 - 10(x + h)

            = 1 - 10x - 10h

s(x + h) - s(x) = 1 - 10x - 10h - (1 - 10x)

                      = 1 - 10x - 10h - 1 + 10x

                      = -10h

= -10
