Answer: 30°

Explanation: so we know line F has to be 180° because it’s a line. it tells us the angle is 140°, so we know the interior angle is 40° because 180°-140°=40°. we also know that a triangle is 180°. so we have the two angles of the triangle: 110° and 40°. to find the third angle we find 110°+40°+?=180°. once we solve, we know the third angle is 30° because 180°-150°=30°.

hope this helped!

Answer:

The answer is "0.586"

Step-by-step explanation:

Please find the solution to the given question:  

z= \frac{0.65-0.61}{\sqrt{\frac{0.65 \times 0.35}{100}+\frac{0.61 \times 0.39}{100}}}

  = \frac{0.04}{\sqrt{\frac{0.2275}{100}+\frac{0.2379}{100}}}\\\\= \frac{0.04}{\sqrt{0.002275+0.002379}}\\\\= \frac{0.04}{\sqrt{0.004654}}\\\\= \frac{0.04}{0.0682202316}\\\\=0.586336327\\\\

Find the value of xx, yy, and zz in the parallelogram below.
Mnenie [13.5K]

Answer: x = 36, y = 10, and z = -25

Step-by-step explanation:

99 and -3z +6 are same side interior angles, so they sum to 180 degrees.

99 -3z + 6 = 180

-3z = 75

z = -25

Opposite angles of a parallelogram are congruent

2x + 9 = -3x + 6

2x + 9 = 75 + 6

2x = 81 - 9

2x = 72

x = 36

9y + 9 = 99

9y = 90

y = 10
