Answer:
Measure of angle b = 35 degrees
Step-by-step explanation:
180 degrees is the total degrees in a triangle, so you have to do 180-80-65
180-80 = 100
100-65 = 35!
Answer:
2√11
Step-by-step explanation:
The square of the hypotenuse (h) of the smaller triangle is given by the Pythagorean theorem:
h² = 6² +8² = 100
The length of x is given by that same theorem:
h² +x² = 12²
x² = 12² -h² = 144 -100 = 44 . . . . . subtract h², fill in its value
x = √44 . . . . . . . . take the square root
x = 2√11 . . . . . . . simplify the root
A triangle has the following coordinates: (8,6), (4,-4), (-9,-2) After a reflection, it has the coordinates (-8,6), (-4, -4), (9

Answer:
The y-axis
Step-by-step explanation:
When the x coordinate changes signs but the y doesn't, it reflects across the y-axis
