What you have to do is add up the amount of total grade scores. 76+99+86+x. You get 261+x. you have to get 99% or higher
The unlabeled part of the right angle is complementary to 68 degrees, so 22 degrees. y is supplementary to 78 degrees, so 102 degrees. z as the third angle in the small triangle is 180 less than the sum of the other two,
z = 180 - 22 - 102
Answer: 56 degrees
Answer:
234 square inches
Step-by-step explanation:
We are given that
Length of book, l=11 in
Width of book, w=8 in
Height of book, h=1in
Additional area required to overlap=20 square inches
We have to find how many square inches of paper to make cover of one book.
We know that surface area of cuboid

Using the formula
Surface area of book


Total paper used to make cover of one book
=Surface area of book +additional surface area
=

Hence, Anwar will use paper to make cover of one book=234 square inches
1.8 - 0.2x = -1.6 Subtract 1.8 on both sides
1.8 - 1.8 - 0.2x = -1.6 - 1.8
-0.2x = -3.4 Divide -0.2 on both sides

x = 17
