Answer:

1). a = 9.42 m

2). b = 6.37 m

3). c = 4.48 m

Step-by-step explanation:

In the figure attached,

By applying tangent rule in triangle ADE,

tan47 = \frac{h}{c}

c = \frac{h}{\text{tan}47}

c = \frac{4.8}{\text{tan}47}

c = 4.476

c ≈ 4.48 m

Now we apply the same rule in triangle ACE,

tan37° = \frac{h}{b}

b = \frac{h}{\text{tan}37}

b = \frac{4.8}{1.0724}

b = 6.37 m

Now apply the tangent in triangle ABE,

tan27° = \frac{h}{a}

a = \frac{h}{\text{tan}27}

a = \frac{4.8}{0.5095}

a = 9.42 m

Diane is 25 years older than her son Craig. The sum of their ages is 105. How old are Diane and Craig?
ankoles [38]

Answer:

Let Craigs age = x

Therefore Dianes age = 25 + x ( since she's 25 years older)

Dianes + Craigs age = (25 + x) + x = 105 (They said both of their ages sums up to 105)

25 + 2x = 105

2x = 80

x = 40

Craigs age is 40 years old.

Dianes age is 65 years old.

The scale drawing of a building has a width of 4 inches and a height of 8 inches. If the width of the actual building is 32 feet
kirill115 [55]
Hello!

First you have to find the scale

32 / 4 = 8

To get the actual building you multiply the scale building by 8 and change the units to feet

8 * 8 = 64ft

The answer is 64ft

Hope this helps!

The equation of the line EF is y=2x+1. Write an equation of a line parallel to line EF in slope intercept form that contains poi
saul85 [17]
Y = 2x + 2

The slope must stay the same since they are parallel and the new point would be the y intercept.
