Answer:
c ≈ 9.43
C = 32 degrees
Step-by-step explanation:
we learn that:
AB^2 = AC^2 + CB^2 so in this case:
c^2 = 5^2 + 8^2
c^2 = 25 + 64
c^2 = 89
c^2 = ^2
c = 9.43
Because ACB is perpendicular angle so it would be 90 degrees
CAB is 58 degrees angle
We know that 3 angle in a triangle must = 180 degrees
So, CBA = 180 - 90 - 58
= 32 degrees
Hope this helped :3
yeah i guess you re right sorry for making confusion
Answer:
x = 5 + √3, 5 - √3
which is 6.73 , 3.27 to the nearest hundredth.
Step-by-step explanation:
(x - 5)^2 = 3
Take the square root of both sides:
x - 5 = +/- √3
x = 5 + √3, 5 - √3
Answer:1. you can compute the slope, m
2. point (0,3) is the y-intercept; b=33
3. y = mx + b, so put the numerical values in for m & b. DON

The value of - 7x - 3(9 - 7x) = - 41 </h2>
Step-by-step explanation:
We have,
- 7x - 3(9 - 7x) ....... (1)
To find, the value of - 7x - 3(9 - 7x) = ?
Put x = - 1 in equation (1), we get
= - 7( - 1) - 3(9 - 7( - 1))
= 7 - 3(9 + 7)
= 7 - 3(16)
= 7 - 48
= - 41
Thus, the value of - 7x - 3(9 - 7x) = - 41
