Answer:
35.54 degrees
Step-by-step explanation:
For A, we have the opposite side (5) and the adjacent side (7). We can use the inverse of tan and to tan⁻¹(5/7) to get 35.54
We use the inverse of tan because tanΘ=opposite/adjacent, and we want to find the angle. We multiply both sides by the inverse bc that's what we would do if it was a number, and then get tan⁻¹(5/7)
Hope this helps. Sorry if I added too much explaination
Answer:
10 i think
Step-by-step explanation:
(-3s +2t)(4s -t) = -12s^2 +3st +8st -2t^2 = -12s^2 +11st -2t^2 so the last one choice is right sure
Answer:
a)3⁴
b)7⁵
c)10²
d)5⁷
Step-by-step explanation:
a)3²×3² = 3^2+2=3⁴
b)7×7⁴=7¹×7⁴=7^1+4=7⁵
c)10⁹÷10⁷=10^9-7=10²
d)5⁸÷5=5⁸-5¹=5^8-1=5⁷
Ratio is a division in its simplest form.
To get the ratio of length to width, divide the two then simplify.
In this case, convert the length and width into decimals.
length = 7 1/2 = 7.5
width 4 3/4 = 4.75
ratio of length to width is;
7.5/4.75 = 750/475
This can now be written as;
750 : 475
Dividing both sides by 25;
= 750/25: 475/25
= 30 : 19
