Answer:
36
Step-by-step explanation:
N^2 + 2N + 1
Since we are given N = 5, we just substitute N for 5
(5)^2 + 2(5) + 1
25 + 10 + 1
36
Answer:
40
Step-by-step explanation:
In the triangle, there is a 90 degree angle and Angle 1 (what we are looking for) and the other angle, lets call is Angle 2.
Lets find Angle 2 first.
First of all, the angle between angle 40 and 90 can be found easily.
That angle (lets call it "x) and 40 and 90 make a straight angle (180 degrees). So we can write:
40 + x + 90 = 180
Lets solve for "x":
40 + x + 90 = 180
130 + x = 180
x = 180 - 130
x = 50
Now, This angle (50) and Angle 2 are same [vertical angles]
So,
Angle 2 = 50
Now, there are 180 degrees in 3 angles in a triangle. So for the triangle shown, we cacn write:
90 + Angle 1 + Angle 2 = 180
90 + Angle 1 + 50 = 180
Angle 1 + 140 = 180
Angle 1 = 180 - 140
<u>Angle 1 = 40</u>
Answer:
The angles are 36° and 144°
Step-by-step explanation:
Let
x-----> one of the angles formed by two intersecting lines
y----> the other angle formed by two intersecting lines
we know that
x+y=180° -----> Equation A (by supplementary angles)
x=4y -----> equation B
substitute equation B in equation A
4y+y=180°
5y=180°
y=36°
Find the value of x
x=4(36°)=144°
therefore
The angles are 36° and 144°
