Answer:
x = 71
Step-by-step explanation:
<B is a right angle, so triangle ABE is a right triangle, and angles BAE and AEB are complementary.
m<BAE + m<BEA = 90
42 + m<BEA = 90
m<BEA = 48
<BEC is a straight angle, so its measure is 180 deg.
m<CED + m<DEA + BEA = 180
61 + x + 48 = 180
x + 109 = 180
x = 71
Answer:
10 feet
Step-by-step explanation: thought it was 11 but got it wrong because it’s 10
Answer:
Radius=4 units
Centre= (0,-10)
Step-by-step explanation:
Given equation of circle is x^2 +(y-10)^2=16
Comparing it with (x-h)^2 +(y-k)^2 = r^2 ,we get,
r=4
Since, centre of a circle=(h,k)=(0,-10)
This is the commutative property
