Answer:
x = 67; y = 40
Step-by-step explanation:
You are correct with y. Angles y + 23 and 63 are vertical, so they are congruent. That gives you y + 23 = 63, which gives y = 40.
To find x, look at angles 2x - 17 and 63.
They are adjacent angles whose outside rays lie on a line. Angles like these are called a linear pair, and they are supplementary. That means their measures add up to 180 deg.
2x - 17 + 63 = 180
2x + 46 = 180
2x = 134
x = 67

Answer:
10 inches
Step-by-step explanation:
Use the formula for the area of a trapezoid. Fill in the given information and solve for the unknown.
A = 1/2(b1 +b2)h
50 in² = (1/2)(3 in +7 in)h
50 in²/(5 in) = h . . . . . . . . . . divide by the coefficient of h
10 in = h
The height of the trapezoid is 10 inches.
what graph?
I don't see it, make sure to upload a file to your question next time.
(x+5)² + (y - 6)² = 16
(x - h)² + (y - k)²= r² is circle centered at (h,k) with radius r.
Answer:
<em>14 </em>° <em>;</em> <em>83 </em>°
Step-by-step explanation:
( 14x - 1 )° + ( 2x + 2 )° = 97°
14x - 1 + 2x + 2 = 97
16x = 96
x = 6
m∠BCA = ( 2 × 6 + 2 )° = <em>14 </em>°
m∠ABC = ( 14x - 1 )° = <em>83 </em>°
