Answer:
117°
Step-by-step explanation:
Angle of straight line is 180°
Angles in a triangle add up to 180°
starting at right
180 - 101 = 79° at right side angle in triangle
now solving left side angle
180 - 38 - 79 = 63°
now solving x using left side angle, must add to 180°
x + 63 = 180°
x = 117°
Answer:
A. 10x+18=48
Step-by-step explanation:
She uses x eggs per cake, and she bakes 10 cakes. She has 18 eggs left over. So the product of the 10 cakes and the number of eggs she used for each cake, plus the 18 eggs left over will get you the ending answer of 48.
Answer:
36.9°
Step-by-step explanation:
As shown in the diagram attached,
θ is the acute angle formed at the intersection of the diagonals of the rectangle.
From the diagram,
tan(θ/2) = 10/30
tan(θ/2) = 1/3
θ/2 = tan⁻¹(1/3)
θ/2 = 18.43
Therefore,
θ = 18.43×2
θ = 36.87
θ = 36.9°
Hence the acute angle formed is 36.9°
