Answer:180 degrees
Step-by-step explanation:Let "x" be the measure of the angle the problem is asking for.
"when twice of a angle is added to 45" is the angle (2x+45) degrees.
The problem says that the angle (2x+45) is the supplement to the given angle.
It means that
x + (2x + 45) = 180 degrees. <<<---=== This equation is the exact meaning of the condition.
Simplify and solve this equation for x:
3x + 45 = 180 ====> 3x = 180 - 45 = 135
====> x = 135/3 = 45 degrees.
Answer:
y=14
Step-by-step explanation:
- the triangle is equilateral triangle
- angle A = angle B
- so we immediately got the answer for x.. x=25
- so 180°-100°=80°
- 5y+10°=80°
- 5y=80°-10°
- 5y=70°
- y=70°/5
- y=14
Answer:
Option 2
Step-by-step explanation:
Height of lemon tree = 8
Height of date tree = 8 x 3
On comparing, we understand that the date tree is 3 times as tall as the lemon tree.
The word problem is based on division ratio so u have to divide by five so 100 divided by five is 20 meaning the collector has to sell 20 band posters.
