Answer:
95
Step-by-step explanation:
let x be his mark in the fourth test, then
mean =
= 83 ( multiply both sides by 4 )
83 + 81 + 73 + x = 332
237 + x = 332 ( subtract 237 from both sides )
x = 95
Answer:
10.6
Step-by-step explanation:
radius = 1.5 height = 1.5 so it's 10.6
The answer is -2,2 for this problem
<A = <C = 73
<B = 180 - (<A + C)
6x + 4 = 180 - 2(73)
6x + 4 = 180 - 146
6x + 4 = 34
6x = 30
x = 5
answer
x = 5
