Answer:
Isosceles triangle has two equal sides and two congruent bases.
Step-by-step explanation:
Isosceles triangle has three sides out of which two are equal. It has two congruent sides. The angle opposite to base is vertex. The two sides of the triangle are congruent and the angles opposite to these sides are also congruent. It is a special type of triangle which is also called equilateral triangle.
Answer: CD = 10
Identify the given information.
FG = 15
GE = 21
FE = 36
CD = x
DE = x + 4
Form your equation. Due to the Side-Splitter Theorem, FG/GE = CD/DE.
15/21 = x/x + 4
Cross-multiply and solve.
15(x + 4) = 21x Distributive Property
15x + 60 = 21x Subtract 15x from both sides
60 = 6x Divide by 6 to both sides
x = 10 Answer!
Answer:
Step-by-step explanation:
Lets break each problem down before we answer it so it help to understand what we are looking for.
Vocabulary:
Unit Rate: how many units of the first type of quantity corresponds to one unit of the second type of quantity. (12 inches to 1 foot)
Unit Rates:
Problem 1: Top left
A boy delivers 189 papers in 3 hours
Unit Rate: 63 papers delivered per hour
In simple terms, all we are doing is creating a fraction then simplifying it :)
Problem 2: Top right
It costs $8.40 for 12 cupcakes
Unit Rate: For every $0.70, it costs one cupcake
Problem 3: Bottom left
5 miles in 50 minutes
Unit Rate: For every one mile ran, it takes 10 minutes
Problem 4: Bottom right
375 passengers distributed between 5 cars
Unit Rate: For ever 75 passengers, there is one car
Hope this Helps!
