Answer:
k = 140°
Step-by-step explanation:
The sum of the interior angles of any triangle = 180°.
64° + 76° + x = 180°
x = 40°
40° + k = 180° because they are supplementary angles
k = 140°
Answer:
y = 13.9
Step-by-step explanation:
It is given that
–5.7 + y = 8.2. -----(1)
Equation (1) is a linear equation in one variable.
LHS consists of a constant and a variable term
RHS consists of only constant term
<u>Find the value of y</u>
Solving the equation
-5.7 + y = 8.2
moving -5.7 to the RHS
y = 8.2 + 5.7
y = 13.9
Therefore the value of y = 13.9
-5.7 + y = 8.2
S = 10x^2
S/10 = x^2
+or-sqrt(S/10) = x
+or- sqrt(S10)/10 = x
so
_inverse = +or-sqrt(10x)/10
15-3(4-2x)-7(x-8) = 15 - 12 + 6x -7x +56 = -x +59
15-3(4-2x)-7(x-8) = - x + 59
