Answer:
3.9 to the nearest tenth.
Step-by-step explanation:
Using the Pythagoras theorem for a right triangle:
8^2 = 7^2 + x^2
x^2 = 64 - 49 = 15
x = √15 = 3.87298
Answer:
1 = 130
2 = 50
3 = 130
Step-by-step explanation:
Since we already know that one angle is 50 degrees, this also tells us that angle two is congruent to it because it is opposite to it. Now the two other adjacent angles, basically just do 180-50 to get 130.
It would be 20 so you had it right

➷ -2x + 3 < 5
Subtract 3 from both sides:
-2x < 2
Divide both sides by -2 to isolate x:
x = -1
