Answer:
A = 18
B = 88
C = 74
Step-by-step explanation:
Givens
B = 3*A + 34
C = A + 56
Equation
A + B + C = 180
Solution
A + 3A + 34 + A +56 = 180 Collect like terms
5A + 90 = 180 Subtract 90 from both sides
5A = 180 - 90
5A = 90 Divide by 4
A = 90 / 5
A = 18
Answer
B = 18*3 + 34 = 54 + 34 = 88
C = 74
Check
A + B + C = 18 + 88 + 74
A + B + C = 180 as it should.
Hello there!
Explanation:
↓↓↓↓↓↓↓↓↓↓↓↓↓
I gave you a hint.
You had to used PEMDAS.
P-Parenthesis
E-Exponents
M-Multiply
D-Divide
A-Add
S-Subtract
First you had to calculate with parenthesis first.
Then you calculate with exponents.
You had to multiply and divide you had go to left to right.
Then you add or subtract you had go to left to right.

Answer:
x=3
Step-by-step explanation:
If k is between J and L, then
JK + KL = JL
2x+11 + (3x) = 13x-13
Combine like terms
5x +11 = 13x -13
Subtract 5x from each side
5x-5x+11 = 13x-5x-13
11 = 8x-13
Add 13 to each side
11+13 = 8x-13+13
24 = 8x
Divide by 8
24/8 = 8x/8
3 =x
Answer:
Acute triangle
Step-by-step explanation:
If you add up are those angle equations, set it equal to 0, 26x - 2 = 180, you get x = 7/ Plug that back into each equation, and you realize none of the angles are more than 90. This makes it an acute triangle.
