Answer:

26˚

Step-by-step explanation:

Since there is already two angles (The square in the corner shows that the angle is 90˚)

So subtract 90˚ with 64˚ which is 26˚

Answer:

this whole angle is equal to 90°

so the value of angle b = 90°-64°

so the value of b= 26.

Where mBD =70° and mCA = 170°

Nookie1986 [14]

Answer:

m∠BPD = 120

mBC + mAD = 120°

Step-by-step explanation:

according to intersecting chord theorem: The measure of the angle formed by two chords that intersect inside the circle is $\frac{1}{2}$ the sum of the chords' intercepted arcs.

m∠BPD = $\frac{1}{2}$ (M∠BD + M∠CA)

= $\frac{1}{2}$ (70 + 170)

= $\frac{1}{2}$ (240)

m∠BPD = 120

We know that a circle has a total of 360° around the center of circle. To find the measure of the remaining measure of angle of arcs, subtract them from the whole that is 360°

mBC + mAD = 360 - ( 70 + 170 )

= 360 - 240

mBC + mAD = 120°

Create an equation to solve for x using the trapezoid midsegment formula:

Serggg [28]

Answer:

Equation for x: 3x - 6 = $\frac{2x - 1 + 25}{2}$

x = 9

CD = 17

GH = 21

Step-by-step explanation:

The midsegment formula for a trapezoid is

GH = $\frac{CD + FE}{2}$

3x - 6 = $\frac{2x - 1 + 25}{2}$

6x - 12 = 2x + 24

4x = 36

x = 9

CD = 2x - 1 = 2(9) - 1 = 18 - 1 = 17

GH = 3x - 6 = 3(9) - 6 = 3 = 27 - 6 = 21
