Answer:
57 deg
Step-by-step explanation:
Rhombus ABCD has diagonals AC and BD which intersect at point E.
The diagonals of a rhombus divide the rhombus into 4 congruent triangles.
If you find the measures of the angles of one of the triangles, then you know the measures of the angles of all 4 triangles.
Also, the diagonals of a rhombus are perpendicular.
Look at triangle BCE.
m<BCE = 33
m<BEC = 90
m<BCE + m<BEC + m<CBE = 180
33 + 90 + m<CBE = 180
m<CBE = 57
<ABE in triangle ABE corresponds to <CBE in triangle BCE.
m<ABE = m<CBE = 57
Answer: 57 deg
The solution to the problem is as follows:
<span>
cot θ = cos θ / sin θ </span>
<span>So sinθ * cot θ = cos θ after cancelling sin θ </span>
<span>Now cosθ + sin θ cot θ = cos θ + cos θ = 2 cos θ

Answer:
4x² + 22x − 1 = 0
Step-by-step explanation:
Start off with the standard formula to finding area with polynomials and quadratic functions.
(2x + 5)(2x + 6)
Work out like a normal binomial.
4 + 22x + 30 - 31
(You're subtracting 31 to take out the minimum of what the frame has to be)
4 + 22x - 1 = 0
A real number and a rational number
Answer:
The slope would be m=0 as it is a straight line.
Step-by-step explanation:
You use the slope intercept formula y=mx+b to find the slope.
