Find the value of x and the measure of each labeled angle. (8x - 20ºX (5x + 37)

11111nata11111 [884]

According to above figure, the angles (8x - 20)° and (5x + 37)° are pairs of vertical opposite angles, so

8x - 20 = 5x + 37

8x - 5x = 37 + 20

3x = 57

x = 57 ÷ 3

x = 19

Given the triangle below, what is the measure of x to the nearest foot?

luda_lava [24]

Answer:

18 ft

Step-by-step explanation:

Since the triangle is right angled ; we could use trigonometry ;

Using the angle , 40° ; adjacent side, = 14 feets ; hypotenus = x

Cos θ = Adjacent / hypotenus

Cos 40 = 14 / x

0.7660444 = 14 / x

0.7660444x = 14

x = 14 / 0.7660444

x = 18.27

= 18 ( nearest foot)

Use the zero product property to find the solutions to the equation x^2+x-30=12

lukranit [14]

Answer:

Due to there being no negatives in this equation, you can pretty much just eliminate the first 3 answers.

However in working out, here is what I did.

x^2 + x - 30 = 12 (+30)

= x^2 + x = 42

Then you can conclude that the answer is D, due to 6 x 6 = 36, plus 7 equaling 42.

How do you solve for 5/6w = 2/3 (the answer is w= 4/5) I just don’t know how to show it.

Readme [11.4K]

Answer:

5/6w=2/3

5/6(4/5)=2/3

20/30=2/3

20/30=10/15=2/3=2/3

Proof:

5/6w=2/3

6/5*5/6w=2/3*6/5

30/30w=2/3*6/5

w=12/15=4/5

Hope this helps ;) ❤❤❤
