Thank you
x = 0.6x + 384
subtract .6x from each side
.4x = 384
divide both sides by .4
x = 960
Answer:
B. 60deg
Step-by-step explanation:
Both the sum of the third angle in the triangle and x has to be 180deg, as they sum to a half angle;
and the sum of angles in any triangle is 180deg.
We know that x = 180deg - (180deg - 28deg - 32deg) = 180deg - 180deg + 28deg + 32deg = 60deg
Also, note that x is drawn as smaller than a right angle. Unless the picture was made specifically to confuse us, we know that the only answer could be B.
Answer:
1 = 52
2 = 68
3 = 40
4 = 25
Step-by-step explanation:
1 = (4 + 3)^2 + (12 / 4)
7^2 + 3
49 + 3
= 52
2 = (12 x 9 - 7^2) + 9
(108 - 49) + 9
59 + 9
= 68
3 = (30 - 2) / 7 + 6^2
28 / 7 + 36
4 + 36
= 40
4 = (2 x 7 + 4^2) - 5
(14 + 16) - 5
30 - 5
= 25
Hope this helps!! Brainliest plz??
