The measures of the angle of a triangle are shown on the figure below. Solve for X.
Answers
Internal angles sum: 180(sides-2) = 180
5x = 180 - (48 + 90 + 17)
x = 25/5
x = 5
answer: 5
proof:
(90 + 48) + (5(5)+17) = 180
Answer:
x=5
Step-by-step explanation:
We know that a triangle consists of 180°. So to start, you take the two given angles and add them together. 48+90=138.
Now you subtract the 138 from the total of 180 to get the degrees of the remaining angle. 180-138=42°.
Now set the unknown angle equal to 42. (5x+17) = 42
Subtract 17from both sides to get 5x=25
Divide 5 from both sides to get x=5

Answer:
1) 6a - 2b
2) 2a + b
3) 2b + a
4) 4b - a
5) 3(a + b)
Step-by-step explanation:
2a + b ==> 2(3) + 5 = 6 + 5 = 11
2b + a ==> 2(5) + 3 = 10 + 3 = 13
3(a + b) ==> 3(3 + 5) = 3(8) = 24
4b - a ==> 4(5) - 3 = 20 - 3 = 17
6a - 2b ==> 6(3) - 2(5) = 18 - 10 = 8
Now order them from least to greatest
6a - 2b ==> 6(3) - 2(5) = 18 - 10 = 8
2a + b ==> 2(3) + 5 = 6 + 5 = 11
2b + a ==> 2(5) + 3 = 10 + 3 = 13
4b - a ==> 4(5) - 3 = 20 - 3 = 17
3(a + b) ==> 3(3 + 5) = 3(8) = 24
