Answer/Step-by-step explanation:

Recall the acronym, SOHCAHTOA.

✔️Cos X = adj/hyp (CAH)

Adj = 10

Hyp = 26

Cos X = 10/26

Simplify

Cos X = 5/13 (as a fraction)

Cos X = 0.3846 (as a decimal to 4 d.p)

✔️Cos Z = adj/hyp (CAH)

Adj = 24

Hyp = 26

Cos Z = 24/26

Cos Z = 12/13 (as a fraction)

Cos Z = 0.9231 (as a decimal to 4 d.p)

Angle XYZ = 2X° and angle PQR = (8X -20)°. If angle XYZ and angle PQR are supplementary, find the measure of each angle. Angle P
Alchen [17]

Answer:

PQR = 140

Step-by-step explanation:

Given

XYZ = 2X

PQR = 8X - 20

Required

Find PQR

Since both angles are supplementary, we have:

XYZ + PQR = 180

This gives:

2X + 8X - 20 = 180

10X - 20 = 180

Collect Like Terms

10X = 20 + 180

10X = 200

Divide through by 10

X = 20

Substitute 20 for X in PQR = 8X - 20

PQR = 8 * 20 -20

PQR = 140

What value of x would make the figure below a parallelogram? please show your work!​
lara31 [8.8K]

Answer:

x = 8

Step-by-step explanation:

Since the sum of all angles of a parallelogram is equal to 360 degrees, <Z + <Y is half of the parallelogram, and therefore <Z + <Y = 180 degrees.

16x-4 + 7x = 180, combine like terms

23x - 4 = 180, add 4 on both sides (isolate variable)

23x = 184, divide 23 on both sides

x = 8
