Answer:
x = 22°
the angles are: 63° and 117°
Step-by-step explanation:
a linear pair of angles total together to be 180°
so:
3x - 3 + 5x + 7 = 180
combune like terms:
8x = 176
divide both sides of the equation by 8:
x = 22°
the angles are: 63° and 117°

Answer:
8.12
Step-by-step explanation:
we first multiply 8 by 12 and we will get 96 as our answer
This is a simple Pythagorean Theorem problem. 7 is the hypotenuse so you would do c^2-a^2=b^2. In this case 7^2-2^2=b^2. 7^2 is 49 and 2^2 is 4 so you have 49-4=b^2. 49-4 is 45. The square root of 45 is 6.70. So x=6.70
10:4
35:14
55:22
10:4 divided by 2:2=5:2
35:14 divided by 7:7= 5:2
55:22 divided by 11:11= 5:2
