Step-by-step explanation:
When two statements are connected with an 'and,' you have a conjunction.
For conjunctions, both statements must be true for the compound statement to be true.
When the connector between two statements is "or," you have a disjunction. In this case, only one statement in the compound statement needs to be true for the entire compound statement to be true.
Step-by-step explanation:
1. Use exterior angles (each adds up to 360) to find interior angles
2. Add this together
3.Take it away from 360
Answer:
9
Step-by-step explanation:
This is a right triangle. We can use the Pythagorean theorem to determine the missing side.
a^2 + b^2 = c^2 where a and b are the legs and c is the hypotenuse
a^2 + 12 ^2 = 15^2
a^2 +144 =225
a^2 = 225-144
a^2 = 81
Taking the square root of each side
a = 9
