The diagram is a map showing a zoo, a planetarium, and a museum. Find the measure of the angle formed at the planetarium. The figure shows a triangle. The vertices are labeled as planetarium, museum, and zoo. A measure of the angle planetarium is given by the formula 8 times x plus 8 degrees. A measure of the angle museum is given by the formula 5 times x plus 7 degrees. A measure of the angle zoo is given by the formula 3 times x plus 5 degrees.

ok i will try help you step by step the sum of angle measure of a triangle equal how many ?

Mercury:

old question but will respond so this can be closed sum of angles in a triangle add up to 180, so add up the angles and sum to 180. then solve for x. however, it's asking for the planetarium angle (8x + 8) so evaluate 8x + 8.
