Question

Средняя линия трапеции равна 45 найдите основания трапеции ,если они относятся как 7:8

Answer 1

Основания 7х, 8х 
средняя линия (7х+8х)/2 = (15х)/2
45=(15х)/2 
15х=90
х=6 

6*7=42
6*8=48

Answer 2

Finding the Bases of a Trapezoid

To find the bases of a trapezoid when the ratio between them is given, we can use the following steps:

1. Let's assume that the smaller base of the trapezoid is represented by x. 2. Since the ratio between the bases is given as 7:8, the larger base can be represented as (8/7)x.

Therefore, the bases of the trapezoid are x and (8/7)x.

Please note that without additional information or measurements, we cannot determine the exact values of the bases. The given ratio only provides a relationship between the bases.
