Step-by-step explanation:

Step 1: Define

Identify and set up

30° + 74° + x = 180°

Step 2: Solve for x

x° = 76 °

Step-by-step explanation:

We know that sum of interior angles of triangle is 180 °.

74 ° + 30 ° + x° = 180 °

combine like terms

104 ° + x° = 180 °

subtract each side by 104°

x° + 104 ° - 104 ° = 180 ° - 104 °

x° = 76 °

3.how is solving radical equations different than solving linear equations?

step-by-step explanation:

answer: solve 5\cdot 2^x=2405⋅2  

x

=2405, dot, 2, start superscript, x, end superscript, equals, 240.

solution

to solve for xxx, we must first isolate the exponential part. to do this, divide both sides by 555 as shown below. we do not multiply the 555 and the 222 as this goes against the order of operations!

\begin{aligned} 5\cdot 2^x& =240 2^x& =48 \\ \end{aligned}  

5⋅2
