Answer:
x=7, angle a= 45 degrees, angle b= 65 degrees
Step-by-step explanation:
All the angles in a triangle must add up to 180. Subtract 70 from 180, add both angle a and angle b to get 16x-2=110, solve for x, x=7. Substitute x out for 7 in the equations then simplify to get angle a=45 and angle b=65
Step-by-step explanation:
The last step is a little wrong. Lemme show you:
x(x + 2) + (x + 2)
Imagine there is an invisible '1' infront of (x + 2) like this:
= x(x + 2) + 1(x + 2)
Now we can combine the like terms together:
= (x + 1)(x + 2)
This is the correct factorization.
Complex numbers are divided into two parts; real and imaginary parts. The value of Z3 is 
Given that:


Since O is the origin, then:

This means that:

So, we have:

Collect like terms


Hence, complex number Z3 is

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
