Sagot :
Answer:
26⁰, 64⁰, 90⁰
Step-by-step explanation:
this is simple perhaps
90⁰+x⁰+(3x-14)=180⁰. (sum of angles in a triangle)
90⁰ + x+3x-14=180⁰
90⁰+4x-14=180⁰
4x + 76= 180⁰
4x= 180-76
4x=104
x=104/4
x=26
(3x-14)= 3(26) -14= 78 -14 = 64⁰
Answer:
26, 64, 90
Step-by-step explanation:
(3x-14) + 90 + x = 180
-90 -90
_________________
(3x-14) + x = 90
Now, combine the like terms. 3x and x are like terms
4x -14 = 90
+14 +14
____________
4x = 104
/4 = /4
x = 26
Input 26 in the equation to find the angle. The place where there is a box, it signifies that this is a right angle triangle and so we automatically know that area is 90 degrees.
