Answer:

Vertical angles are congruent and have equal measures. Therefore,

Simplify and solve for x :

x + 16 = 4x -5.

16=3x-5

21=3x

x=7

Thus the angles measure is  x+16 = 7+16 = 23 degrees, for both angles (for each of the two vertical angles).

Step-by-step explanation:

each angle measure is 23 degrees

Find the length of side xz give your answers to 3 significant figures
aleksandrvk [35]

Answer:

XZ ≈ 14.4 cm

Step-by-step explanation:

Using the cosine ratio in the right triangle

cos29° = \frac{adjacent}{hypotenuse} = \frac{ZY}{XZ} = \frac{12.6}{XZ}

Multiply both sides by XZ

XZ × cos29° = 12.6 ( divide both sides by cos29° )

XZ = \frac{12.6}{cos29} ≈ 14. 4 ( to 3 sig. figs )

Find the slope of the line that passes through the points (-2,4) and (-5,-6)
natali 33 [55]

\bf (\stackrel{x_1}{-2}~,~\stackrel{y_1}{4})\qquad (\stackrel{x_2}{-5}~,~\stackrel{y_2}{-6}) \\\\\\ slope = m\implies \cfrac{\stackrel{rise}{ y_2- y_1}}{\stackrel{run}{ x_2- x_1}}\implies \cfrac{-6-4}{-5-(-2)}\implies \cfrac{-10}{-5+2}\implies \cfrac{-10}{-3}\implies \cfrac{10}{3}

Find the values of x and y
Anastasy [175]

Answer:

X=20

Y=70

Step-by-step explanation:

All angles within a triangle add up to 180

180 - 40 = 140

140 is the top angle of the big triangle

140 + x + x = 180

x = 20

Now use x to find y by subtracting from the right angle (90 degrees)

90 - 20 = 70

70 + 40 + y = 180

Y = 70
