Answer:
13 inches and 10 inches
Step-by-step explanation:
First, let's find the factor pairs that make up the area of 130 square inches.
Next, let's see the factor pairs that make a perimeter of 46 inches by using the formula 2(l + w).
- 2(1 + 130) = 2(131) = 262
- 2(2 + 65) = 2(67) = 134
- 2(5 + 26) = 2(31) = 62
- 2(10 + 13) = 2(23) = 46
Therefore, the dimensions of the folder are 13 inches and 10 inches.
Answer:
sin(3π/7 - 2π/21)
Step-by-step explanation:
Given
sin 3π /7 cos 2π/ 21 − cos 3π/ 7 sin 2π/ 21
Required
Write a trigonometry formula for the expression
Using sine formula, we have:
sin(A - B) = sinAcosB - cosAsinB
The above formula can be applied to the given expression where
A = 3π/7
B = 2π/21
So, the trigonometry formula is:
sin 3π /7 cos 2π/ 21 − cos 3π/ 7 sin 2π/ 21= sin(3π/7 - 2π/21)
2 3/4=11/4
1 3/4=7/4
11/4+7/4=18/4....18(2)/4(2)=9/2.......4 1/2
Answer:
Step-by-step explanation:
if sum of two angles 180 degree then is called is called supplementary angles.
here , one angle is 118 degree . Let the other angle be x
x + 118 = 180 degree
x = 180 - 118
x = 62 degree
therefore , the measure of other angle is 62 degree.
