Answer:

x = -13

Step-by-step explanation:

Let the number be x. ATQ,

\dfrac{3}{4}(x-7)=-15

The above equation shows Three-fourths of the difference of a number and 7 is negative fifteen. We need to find the number.

cross multiplying both sides,

3(x-7)=-60\\\\x-7=-20\\\\x=-20+7\\\\x=-13

So, the number is -13.

Solve the triangle. A = 46° a = 33 b = 26
frozen [14]
Using sin rule:
a/sin A =b/sin B=c/sin c
SIN A=sin 46=0.72
THEN:sin B =(0.72*26)/33=0.57
then B= 34° 
AS the sum of triangle angles=180 
then C=180-(46+34)=100°
then c =(a*sin C)/sin A
sin C=sin 100=0.98
=(33*0.98)*0.72=45
