Answer:
right
Step-by-step explanation:
69 + 21 is equal to 90 and all three angle of a triangle will be 180 so the last angle would be 90. And a right triangle will have an angle = to 90
Answer:
Step-by-step explanation:
You can use the foil technique (first outer inner last)
(3x - 1)(-x + 4) = (3x · (-x)) + (3x · 4) + ((-1) · (-x)) + ((-1) · 4)
=

Square root of 65 or 8.06 to the nearest hundredth.
Step-by-step explanation:
We use the Pythagoras Theorem ( Distance Formula):
This = √ [( x2 - x1)^2 + (y2 - y1)^2 ]
= √ [( 3 - -4)^2 + (-1 - -5)^2]
= √ (7^2 + 4^2)
= √65
= 8.06 to the nearest hundredth.
