You got the equation right, but I think it would like you to solve for the variable especially in #3 since it asks 'what is the number'
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:
1
Step-by-step explanation:

Using BODMAS we'll have to solve what is in the bracket first

Multply -7 by 5 still using the rule of BODMAS
