∠ A = 31.3°, ∠ C = 58.7°

Step-by-step explanation:

Using the sine ratio in the right triangle

sin A = = = , thus

∠ A = ( ) ≈ 31.3° ( to the nearest tenth )

The sum of the 3 angles in a triangle = 180° , thus

∠ C = 180° - (90 + 31.3)° = 180° - 121.3° = 58.7°

x+y=90

x=30-y=x

step-by-step explanation:

if you understand you will get the answer

26 is 33.33% of 78

step-by-step explanation:

26 is what percent of 78?

26 is p% of 78

equation: y = p% * x

solving our equation for p

p% = y/x

p% = 26/78

p = 0.3333

convert decimal to percent:

p% = 0.3333 * 100 = 33.33%
