Answer:
1. c = 13
2. a = 20
Step-by-step explanation:
1. 12² + 5² = x²
144 + 25 = x
144 + 25 = 169
√169 = 13
2. 29² - 21² = x²
841 - 441 = x
841 - 441 = 400
√400 = 20
Answer:
A) 8 38/44
Step-by-step explanation:
Find Least Common Multiple
3 2/4 + 5 4/11
= 3 22/44 + 5 16/44
= 8 38/44
Answer:
The value of x is 75
Step-by-step explanation:
First we need to find the other angle that doesn't have a number in it.
To find the degrees of the other angle we subtract 155 from 180.
180 - 155 = 25
Now we have to find the value of x. Add 80 and 25 together to get 105. A triangle is going to be 180 degrees. Subtract 105 from 180.
180 - 105 = 75
Now we will add 80, 25, and 75 to check our work.
80+25+75 = 180
1/3x4x4x8xpi=128/3pi
Second option is the answer.
A= -2
because u can add 6 and 3 and move it to other side to divide
