Answer:
1) 35
2) 125
Step-by-step explanation:
1)
angle adc = x
x+ 90 + 20 = 180 (triangke sum property)\
x = 180 - 110 = 70
angle bdc = 70/ 2 = 35 ( the median cuts the angle into 2)
2) cbd = x = 125
x + c + bdc = 180
x + 35 + 20 = 180
x = 180 - 55 = 125
I hope im right!!!

Answer:
7/7 also known as a whole (1)
Step-by-step explanation:
All you have to do is add 4 and 3 then keep the denominator the same (7)
4t=r
a=pir^2
sub 4t for r
a=pi(4t)^2
a=pi16t^2
a(t)=16pi(t^2)
A. a(t)=16pi(t^2)
B. sub 4 for t
a(4)=16pi4^2
a(4)=16pi16
a(4)=16*16*3.14
a(4)=803.84 square units
A. a(t)=16pi(t^2)
B. 803.84 square units
