Answer:
∡BCE = 60
Step-by-step explanation:
Here, we want to find the angle marked BCE
From our diagram, the angle marked BCE is y
Looking at triangle BCE, we have the right angle, an angle measure of 30 and the angle marked y which we say is BCE
mathematically, the sum of all these will give 180 as the sum f the interior angles of a triangle is 180
Thus, we have that;
y + 30 + 90 = 180
y = 180-120
y = 60
Answer:
what
Step-by-step explanation:
Answer:
x = - 6
Step-by-step explanation:
given the 2 equations
3x + 5y = - 13 → (1)
2x - 3y = - 15 → (2)
To eliminate y from the equations we require their coefficients to be equal so that when we add the equations y is eliminated
multiply equation (1) by 3 and equation (2) by 5
9x + 15y = - 39 → (3)
10x - 15y = - 75 → (4)
add (3) and (4) term by term
(9x + 10x) + (15y - 15y) = (-39 - 75 )
19x = - 114 ( divide both sides by 19 )
x = - 6
To find y substitute x = - 6 into either (1) or (2)
