Work out the size of the angle marked t
tiny-mole [99]

Answer:

<h2>35°</h2>

Step-by-step explanation:

This is an isoceles triangle

And as we all know an isoceles triangle has two equal base angles.

And we also know that the sum of all interior angles of the triangle is 180°

So based on this we can form an algebraic equation of solve for angke t (Let's do it :))

110 + 2t = 180 \\ 2t = 180 - 110 \\ 2t = 70 \\ t  =  \frac{70}{2}  \\ t = 35

So the base angle is 35°

Therefore you would multiply her hourly income (12) by the amount of hours she works (h). Then, add her 30 dollars to it. (Im feeling nice so the answer should look like this ~  12h + 30.) Hope it helps you <3!
