Answer:
x = 37
Step-by-step explanation: Every angle in a triangle adds up to 180, so we can set up an equation where (x + 48) + (x + 58) = 180. From here, we can combine like terms to get 2x + 106 = 180. 180-106 is 74. 74 divided by 2 is 37. So, x = 37.
The answer is probably isosceles, because if the angles and congruent, the sides are congruent as well.
Answer:
29.7 for question 14
15a is 12.1
15b is 14
Step-by-step explanation:
In a 45 45 90 triangle, the legs are congruent, or the same length.
If we call the legs a, then the hypotenuse would be root 2 a.
So if the hypotenuse is 42, we divide by root 2 to get the length of each leg.
That should give us 29.7
In a 30, 60, 90 triangle, the short side is a, then the hypotenuse is 2a, and the longer side is a root 3.
So if the shorter side is 7, the longer side is 12.1, and the hypotenuse is 14.
Answer:
you solve what is inside the parenthesis first to get rid of it, then its almost like you got rid of it.
