Answer:
similar triangles
Step-by-step explanation:
First of all, what are similar shapes? Well, two shapes are similar if you can turn one into the other by moving, rotating, flipping, or scaling. That means you can make one shape bigger or smaller. In this case, we know that triangles ABC and DEF are mathematically similar. The area of triangles ABC is , so we need to know the area of triangle DEF.
From math, let's call the scaling factor, so we know that for any similar figures, the ratio of the areas of any are in proportion to . In other words, if is the area of triangle ABC, and is the area of triangle DEF, then we can write the following relationship:
Twice as long as little drop...
Answer:
Approximate marks sally get = 95%
Step-by-step explanation:
Given:
Sally's study time = 1.5 hour = 1.5 × 60 = 90 minute
Find:
Approximate marks sally get.
Computation:
Number of minute sally study = 1.5 × 60
Number of minute sally study = 90 minutes
Using graph,
Vertical line on 90 minutes shows 95% , we can say that the person who study 90 minutes per day get 95% marks
So,
Approximate marks sally get = 95%
Answer:
The answer is 210°.
Step-by-step explanation:
Given that ∠BOE = 130° and ∠COB is 80°. So in order to find ∠CBE, you have to add up together :
∠CBE = ∠BOE + ∠COB
∠CBE = 130° + 80°
∠CBE = 210°
