Answer:
240 units squared
Step-by-step explanation: Pythagorean theorem and then multiply base times height / 2
Answer:
∠B=60°
Step-by-step explanation:
In this right traingle, using angle B, you have the opposite side which is 6√102, and the adjacent side which is 6√34. Using SOHCAHTOA this invlolves TOA so tangent B = OPPOSITE/ADJACENT or tan B = 6√102/6√34. Simplifying gives tan B=√3. You can use your calculator to solve for B by taking the inverse tangent of √3 or you can use the known trig ratios from the unit circle if you have already learned that to find that angle B is 60°
Answer:

Step-by-step explanation:
To solve this type of problems first need to review some laws of exponents:
When you are multiplying the same base, you need to add the exponents.

When you are raising a base with power to another power, you should keep the base and multiply the exponents:

Now for the expression 
Write the multiplying factors:

Multiply the term 

Then multiply the term 

Simplify the exponents:

Add like terms:
