Step-by-step explanation:
Here. ...the sum of interior angle of triangle is 180° so...
90° + 43° + y = 180°.
133° + y = 180°
y = 180° - 133°
y = 47°
(x + 2) = 3
-2 -2
0 1
x = 1
Answer:
15 ft
Step-by-step explanation:
Pythagoras formula for a triangle with a 90 degree angle :
a^2 + b^2 = c^2
c is the side opposite of the 90 degree angle. exactly or situation here.
=> 9^2 + 12^2 = x^2
=> 81 + 144 = x^2 = 225
=> x = sqrt(225) = 15
68 students increased by 125% is
68 + 68(1.25)
68 + 85 = 153
hope it helps
