13.

<3 = 180 - <1

<3 = 180 - 90

<3 = 90°

14.

<8 = 180 - <6

<8 = 180 - 137

<8 = 43°

15.

<4 = 180 - <2

<4 = 180 - 34

<4 = 146°

Solve for x. -(-2-5x) + (-2) = 18 x= -90 x=-18/5 2 = 18/5 x= 90

mart [117]

Answer:

$x=\frac{18}{5}$

Step-by-step explanation:

$-\left(-2-5x\right)+\left(-2\right)=18$

Add 2 to both sides:

$-\left(-2-5x\right)-2+2=18+2$

$-\left(-2-5x\right)=20$

Divide both sides by -1:

$\frac{-\left(-2-5x\right)}{-1}=\frac{20}{-1}$

$-2-5x=-20$

Add 2 to both sides:

$-2-5x+2=-20+2$

$-5x=-18$

Divide both sides by -5:

$\frac{-5x}{-5}=\frac{-18}{-5}$

$x=\frac{18}{5}$

TS is the height of a building. PQR is a pole in front of the building. QT is a horizontal cable that supports the pole to the b

Iteru [2.4K]

Answer:

The answer is 65.75

Step-by-step explanation:

Since tq is perpendicular to PR then qtsr becomes square

Then

$qr = 30 \: \: \: \: \: and \: qt = 30 \\$

Since the triangle pqt is right angled

Then

$pq = qt \tan(50) = 30 \times \tan(50 ) = 35.75$

Then the height of the pole is equal to

$pq + qr = 35.75 + 30 = 65.75$
