Ok so its 8 `1&8 2&7 3&6 4&5 and then all of those numbers reversed
18 27 36 45 and 81 72 63 54
Answer:
90 degrees
Step-by-step explanation:
Angle BGD is supplementary with angle DGE.
BGD + DGE = 180
Since angle DGE is a right angle, then Angle BGD must also be a right angle:
BGD + 90 = 180
BGD = 90
Answer:
90
Step-by-step explanation:
Let x be Dany's score in geography. His score in chemistry is double his score in geography and it is equal to
2 x
The average of all four scores is 79. Hence
(93 + 88 + x + 2 x) / 4 = 79
Multiply both sides of the equation by 4
4×(93 + 88 + x + 2 x) / 4 = 4×79
Simplify
93 + 88 + x + 2 x = 316
Group like terms
3 x + 181 = 316
Solve for x
3 x = 135
3 x / 3 = 135 / 3
x = 45
score in geography = x = 45
score in chemistry = 2 x = 2 × 45 = 90
Hope it helped u if yes mark me BRAINLIEST!
Tysm!
