construction of an angle bisector
of 60° into 30°and 30°
Answer:
44
Step-by-step explanation:
1) we know that opposite sides of a parallelogram are congruent so
4x+28=10x+4
2) subtract 4 on both sides
4x+24=10x
3)subtract 4x on both sides
24=6x
4)divide by 6 on both sides
4=x
5)substitute for x
length of RS =10(4)+4
length of RD=44
Answer:
A = 78.5
Step-by-step explanation:
to find the area of a quarter of a circle, find the area of the whole circle and divide it by 4:
A = (π) ÷ 4
A = (3.14 x ) ÷ 4
A = (3.14 x 100) ÷ 4
A = 314 ÷ 4
A = 78.5
To calculate %, just remember "Is Over Of" i<span>n this case, is = 90, and of = 36 </span><span>So, 90/36 = 2.5, or %250.</span>
