(2x+1)+89=180. 180 is the angle of a straight line. Set your two known sides equal to 180 and solve for x if needed.
Answer:
14
Step-by-step explanation:
As long as two sides of a triangle added together are larger than the third side, it is an accurate triangle!
3/4 - 3/5 first we need to change it to the same denominator so it’ll be
15/20- 12/20 which equals 3/20
19.37cm is 74.5% of 26cm so we then we need to take away 19.37 from 26cm that leaves us with 6.63
hope i helped was quite hard just remember the way i did it
Answer: 11.46
Step-by-step explanation:
Formula for calculating the length of an arc is theta/360 ×2Πr. Where;
length of the arc (L) = 9
Theta= 45°
L = theta/360 × 2Πr
9 = 45/360× 2Πr
9 = 1/8 × 2Πr
9 = Πr/4
Πr = 36
r = 36/Π
r = 11.46
Substituting we have,
9 = r × 45°
r = 9/45
