Thats easy its x = 5 , 4 times 5 is 20 minus 2 equals 18
have a nice day
Answer:
True: the leading coefficient in the monomial is -7
Step-by-step explanation:
Math
The measure of ∠4, ∠3 and ∠7 are 115°, 65° and 65° respectively.
<h3>
Equation</h3>
An equation is an expression used to show the relationship between two or more numbers and variables.
From the diagram:
∠2 + ∠4 = 180° (sum of angles in a straight line)
∠4 + 65 = 180
∠4 = 115°
b) ∠2 = ∠3 (vertically opposite angles)
∠3 = 65°
c) ∠3 = ∠7 (corresponding angles)
∠7 = 65°
The measure of ∠4, ∠3 and ∠7 are 115°, 65° and 65° respectively.
