Supplementary means they equal 180 when added. Therefore:
X+56+3x=180
Combine common units
4x+56=180
Subtract 56 from both sides
4x=124
Divide by 4
X=31
Now we know the smaller angle is 31 degrees. Now we plug that into the larger angle:
3(31)+56
93+56
149
The larger angle is 149 degrees.
I hope this Helps!
Answer:
X=-1
Step-by-step explanation:first you distribute 2 to x and 6 which equals 2x+12=10 then you subtract 12 from 10 which equals 2x=-2 then divide -2 by 2x to see what x equals so x=-1
*Use the Pythagorean Theorem
a^2 + b^2 = c^2
6^2 + 5^2 - c^2
36 + 25 = c^2
61 = c^2 *Square root 61
c^2 (c squared) = about 7.8
First calculate the total price of the car alarm
P = 325 + 0.12(325)
P = $ 364 is the total prize of the car alarm
then calculate the discounted price
35%-off sale
P = 364( 1 - 0.35)
P = 364(0.65)
P = $ 236.6
$ 100 coupon
P = 364 - 100
P = $ 264
so it is better to have the 35%-off sale
so the answer is A
Answer:
53°
Step-by-step explanation:
With reference angle A
perpendicular (p) = 9.6
base (b) = 7.2
Now
tan A = p / b
tan A = 9.6 / 7.2
A = tan^ - 1 ( 9.6 / 7.2)
A = 53°
Hope it will help :)❤
