To solve for the value of y, all you have to do is add up all the expressions and values together and make it equal to 180 degrees.
Y + (Y - 12) + 56 = 180
2Y - 12 + 56 = 180
2Y + 44 = 180
Y = 68 degrees.
See the diagram below.

is the height, and

is the slant height.
The height is the distance from the
base of the pyramid to the vertex (the top of the pyramid). It runs perpendicular to the base.
The slant height is the distance from the
base of the triangles which make up its sides to the vertex. It runs perpendicular to this base as well.
Answer:
$1,045
Step-by-step explanation:
40×22=880
22÷2=11
11+22=33
33×5=165
165+880=1,045
Answer:
?
Step-by-step explanation:
The given triangle is a right angle .
In this triangle for angle A side AC is adjacent side ,BC is opposite side and AB is hypotenuse.
Sin of any angle is the ratio of opposite and hypotenuse .

Substituting the values of opposite and hypotenuse
SinA=
