Answer:
y=-2
Step-by-step explanation:
you are solving for the variable y
add 3 to the opposite side, so it cancels out
y=-5+3
y=-2
first one since it’s 1/16 simplest form or 11/17 cuz it’s obv
Answer:
27, 90 and 63
Step-by-step explanation:
Given
Ratio of triangle sides

Required:
The length of each side
Triangles in a triangle add up to 180.
The side with ratio 3 is:




The side with ratio 10 is:




Lastly:
The side with 7 as its ratio




Hence, the angles are: 27, 90 and 63
Answer:
60
Step-by-step explanation:
b = the hypotenuse of a right angle triangle
a = the adjacent side.
R is being defined by the cosine
cos(R) = adjacent / hypotenuse
adjacent = 16* sqrt(2)
hypotenuse = 32*sqrt(2)
Cos(R) = 16*sqrt(2) / 32*sqrt(2) sqrt(2) cancels.
cos(R) = 1/2
R = cos-1(1/2)
R = 60 degrees.
The area of the parallelogram is 40 centimeters
