for positive acute angles A and B, it is known that cos A=20/29 and sin B=60/61. Find the value of sin(A+B) in simplest form.

Step-by-step explanation:

sin(A+B) = sinA cosB + cosA sinB ------(1)

First we will find sinA and cosB

Substitute all values in (1)

8 2/3 is the answer

step-by-step explanation: just use a calculator

let x be the money she spent so that she can earn the free t-shirt.

since, she already spent $112.49

⇒

also, as per the statement: jennifer must spend $250 or more in order to qualify for a free t-shirt at the store.

then,

we have an inequality i.,e

subtract 112.49 from both sides we get;

therefore, $137. 51 more money does jennifer need to spend so that she can earn the free t-shirt
