Important notes:

3 sides 1 angle - COSINE RULE

2 sides 2 angle - SINE RULE

since, the question wants to find the length of BC. In the end we will have 3 sides and 1 angle and use cosine rule

formula of cosine rule:

a² = b² + c² - 2bc Cos A° (to find the length)

Cos A° = b² + c² - a² / 2bc ( to find the angle, if there is given three sides and have to find the angle)

So just substitute,

a² = 13² + 15² - 2(13)(15) Cos 95°

a = 20.6 or 21

Alex777 [14]

Answer:

75 and 552 =627

Step-by-step explanation:

First=x

Second 7x+27

x+ 7x+27= 627

8x+27=627

8x=600

x=75

75*7+27 =525

525+27 = 552

The area of a rectangle is 30 square feet. The base of the rectangle is 7.5

BigorU [14]

Answer:

4 ft

Step-by-step explanation:

<h3>Area of rectangle:</h3>

Area = 30 square ft

base = 7.5 ft

$\sf \boxed{height \ of \ rectangle = \dfrac{Area}{base}}$

$\sf =\dfrac{30}{7.5}\\\\=\dfrac{30*10}{7.5*10}\\\\=\dfrac{300}{75}\\\\= 4 ft$
