So I think the answer to m<5 is 75 degrees
Answer:
√(36+9) = √45 = 6.7 this is the answer, just estime it
I'm assuming you want us to solve for the unknown variable z

Combine like terms on the right side

Use the distributive property on the left side

Add both sides by 20 to cancel out the "-20" on the left side

Divide both sides by 10

That is the value of the known variable, z, in this equation. Let me know if you need any clarifications, thanks!
