5 · (7 - 4)² : 3 + 11 = 5 · 3² : 3 + 11 = 5 · 9 : 3 + 11 = 45 : 3 + 11= 15 + 11 = 26


5 · (7 - 4) · 2 : 3 + 11 = 5 · 3 · 2 : 3 + 11 = 15 · 2 : 3 + 11 = 30 : 3 + 11 = 10 + 11 = 21

The answer is A I just need help working it out
nordsb [41]
STU + STR = 180
8x + STR = 180 [ STU = 8x ]
STR = 180 - 8x

STR = SRT [ RS ≈ ST ]

Now, In ΔSRT,
we have, RST = 7x - 54, STR = SRT = 180-8x
Their sum is 180, as it constitutes a triangle.

7x-54 + 2(180-8x) = 180
7x - 54 + 360 - 16x = 180
 306 - 9x = 180
9x = 306 - 180
9x = 306 - 180
x = 126/9
x = 14

So, option A is your answer.

Hope this helps!
