Answer:
x = 3
Step-by-step explanation:
since it's hitting 3 on the x axis and just goes up and down where 3 is, all the points have an x of 3 and nothing else. making the equation x = 3
ΔADB is a right triangle at ∠D
So, AB ⇒ Hypotenuse & AD,DB ⇒ Legs
∴
ΔADC is a right triangle at ∠D
So, AC ⇒ Hypotenuse & AD,DC ⇒ Legs
∴ BC= BD+ DC = 16 + 9 = 25
∴ The perimeter of triangle ABC = AB + BC + CA = 20 + 25 + 15 = 60.
<u>So, The correct answer is option C. 60</u>
Answer:
x=10
Step-by-step explanation:
It's a 90 degree angle.
90-60=30
30=the remaining angle, 3x
x=30/3, or 10
Hope I helped!
Raymar ate 1/4. That leaves 3/4 left. Kalen ate 1/4 of the 3/4 left. We need to find how much 1/4 of 3/4 is, so we have to divide 3 by 4. To make this easier to solve, we need to change the form of the fractions to make it in sixteenths instead of fourths. So Raymar ate 4/16 leaving 12/16 left and Kalen ate 1/4 of the 12/16 left.This means we can divide 12 by 4 and get 3. Kalen ate 3/16 of the entire pan. Or just draw a diagram similar to this.
