Answer:
3.92 approximately 4
Step-by-step explanation:
let us first find angle at F
40⁰+50⁰+F= 180 (sum of angles in a triangle)
90⁰+F= 180⁰
F= 180⁰-90⁰
F = 90⁰
using sine rule
3/sin 50 = x/sin 90
3/0.7660= x/ 1
0.7660x=3
x= 3/0.7660
x= 3.92 approximately 4
Answer:
x=6 or x=2
Step-by-step explanation:
Answer: 51
Step-by-step explanation: (sqrt(2))^2 + 7^2
The squareroot and square cancel, leaving 2. 7^2=7*7=49
49+2=51
Answer:
17.25
Step-by-step explanation:
You already know y = 72, so you could rewrite the equation to 72 = 4x + 3. To get to the answer, you need to find what X is. What you should do is subtract 3 from both sides, get 69, divide by 4 on both sides and get 17.25
I'm not sure if this is correct, but I hope this helped.
