The total measure of all the angles in a triangle is 180°.
Since there is already a 90° angle, the other 2 angles must also add up to 90°.
The only answer that fits is x = 9.
Check:
9x7 = 63°
3x9 = 27°
Add up = 90°

Answer:
B
Step-by-step explanation:
Unit rate means one quantity in terms of another unit quantity. In the answer choices, we see that the denominator is always in terms of UNIT LITERS (1 L), so that means, we have to find gallons in terms of UNIT LITERS.
It means, we have to divide gallons by liters to get in terms of unitary liters.
Let's check the first line:
19.5/75 = 0.26 Gallons / 1 Liter
Now, checking 2nd:
39/150 = 0.26 Gallons / 1 Liter
So, yes, they are the same and other 2 lines would be the same as well. The unit rate is:
0.26 gal/1L
That's answer choice B
Answer:
Brian will have £817.8
Step-by-step explanation:
Principal = £4700
interest = 5.5% = 0.055
n = 3 years
Amount = [(Principal * (1 + interest)ⁿ) - Principal]
Amount = [(4,700 * (1 + 0.055)³) - 4,700]
Amount = [(4,700 * (1.055)³) - 4,700]
Amount = [(4,700 * 1.174) - 4,700]
Amount = [5,517.8 - 4,700]
Amount = £817.8
