Answer:
she is correct
Step-by-step explanation:
Answer:
2/3
Step-by-step explanation:
To find the slope, we use the formula
m = ( y2-y1)/(x2-x1)
= ( -8 - -10)/( 15 -12)
= ( -8+10)/( 15-12)
= 2/3
Answer:
421/6 degrees
Step-by-step explanation:
The acute angles of a right triangle are complementary, so

So, the acute angles measures 421/6 degrees and 119/6 degrees, and thus the larger angle is 421/6 degrees.
