Answer:
84 degrees
Step-by-step explanation:
Applying the Cosine Rule (Choice 2 is the correct one) :-
12^2 = 11^2 + 6^2 - 2*11*6 cos Y
144 = 121 + 36 - 132 cos Y
cos Y = (121 + 36 - 144) / 132
cos Y = 0.09848
Y = 84.3 degrees
Answer:
48
Step-by-step explanation:
1200/25=48
Answer:
a = 6, b = - 12
Step-by-step explanation:
Expand the left side and compare the coefficients of like terms to those on the right side.
a(4x - 10) ← distribute parenthesis
= 4ax - 10a
Compare to 24x + 5b , then
4a = 24 ( divide both sides by 4 )
a = 6
Then
5b = - 10a = - 10(6) = - 60 ( divide both sides by 5 )
b = - 12

Step-by-step explanation:
The midpoint M of two endpoints of a line segment can be found by using the formula

where
(x1 , y1) and (x2 , y2) are the points
From the question the points are
(-5,6) (8,-6)
The midpoint is
