Answer:
Step-by-step explanation:
3x + x + 60 = 180.
first, we add the x's together.
4x + 60 = 180
then we see if they all have a common multiple. in this case, they do. they are all divisible by 4, so we can use that.
x + 15 = 45
then, just subtract 15 from both sides, that way we get the variable by itself.
x = 30
also, it is a right triangle. the top angle (3x) multiplied by 3 is 90. any triangle that has a 90 degree angle is automatically a right triangle.
The options can be rewrited as follow:
A. 5<4
B. 5<5
C. 5<4
D. 4<-5
∴ Answer is none of the above.
Unless perhaps you have written down the question incorrectly.
Answer:
D) justified, assuming that the test was given fairly
