In parallelogram ABCD, the measure of angle A=3x and the measure of angle B =x+10. What is the measure of angle D?

Alinara [238K]

Answer: 52.5

Step-by-step explanation: 2(3x+10)+2(x+10)=360 because all the sides of a rhombus equal 360 and alternate sides are equal

8x+20=360

-20=-20

8x/8=340/8

x=42.5

x+10. 42.5+10=52.5

D=52.5

*100 points* A circle has a diameter with endpoints (-7, -1) and (-5, -9).

earnstyle [38]

Diameter

√(-7+5)²+(-1+9)²
√2²+8²
√4+64
√68
2√17

Radius

2√17/2
√17units

Now

Centre

(h,k)

(-7-5/2,-1-9/2)
(-12/2,-10/2)
(-6,-5)

Equation

(x-h)²+(y-k)²=r²
(x+6)²+(y+5)²=(√17)²
(x+6)²+(y+5)²=17

Option A
