You need to know what type of triangle it is , all your triangles are right angles that means that they are 90° so you just need to subtract the number that its given from 90° ex
the first problem you just have to do this
21° - 90° = 79 °
so x = 79°
I’m thinking A but you can always look up x and y coordinate graphs to double check
Answer:
Regular proof is a method of proving the statement directly. In this method, we just proved it by using direct formula or theorem. whereas, Indirect proof is a way of proving by contradiction
Step-by-step explanation:
Answer:
Answer is -55
All you have to do is write out the expression. Write it out again this time substitute the a for -6 and the b for -5. After that multiply both and you should have -30 + -25. Add the two negatives and you should have -55.
He was suppose to distribute the 2 to the -4 and make -8
It should have equaled: 3 + 4x - 8
The answer would be 4x-5
