Answer:#1 C.30 #2 40
Step-by-step explanation:
3x+15=7x-5
3x+15+5=7x-5+5
3x+20=7x
3x-3x+20=7x-3x
20=4x
20/4=4/4x
5=x so if it is an equilateral all sides are equal so 3(5)+15=30 so the answer should be 30
So the triangle in #2 is an isoceles so two of the angles are equal so the equation is 2(2x-24)+3x+4=180
4x-48+3x+4=180
7x-44=180
7x=224
x=32
2(32)-24
64-24=40
Hi there, to solve this all we do is divide 7 by 16. 7÷16=0.4375=43.75. Therefore, 7/16 as a percent is 43.75%
Answer:
1 to 100,000
Step-by-step explanation:
Centimeters and kilometers are scales of the official unit of length in the SI, the meters.
In a meter there are 100 centimeters, and in a kilometer there are 1000 meters, so in a kilometer there are 1000(100)cm ⇒ 100,000cm
So the scale of 1 centimeter to 1 kilometer is:
1 to 100,000
Answer:
62° and 96°
Step-by-step explanation:
The exterior angle of a triangle is equal to the sum of the 2 remote interior angles.
Let x be the other remote interior angle, then
22 + x = 84 ( subtract 22 from both sides )
x = 62
The sum of the 3 angles in a triangle = 180°
Subtract the sum of the 2 known angles from 180 for third angle
third angle = 180 - (62 + 22) = 180 - 84 = 96
The other 2 interior angles are 62° and 96°
