What is the total number of an acute angle?

The measure of an acute angle is between 0 and 90 degrees (more than 0, less than 90).The measure of an acute angle is between 0 and 90 degrees (more than 0, less than 90).The measure of an acute angle is between 0 and 90 degrees (more than 0, less than 90).The measure of an acute angle is between 0 and 90 degrees (more than 0, less than 90).


A quadrilateral has two 90 degree angles and a 91 degree angle What is the measure in degrees of the fourth angle of the quadrilateral?

4 sides requires Total interior angles of 360 degrees 360-90-90-91= 89


What is angle E to the nearest degree in the triangle EFG where FG is 89 inches EG is 77 inches and angle G is 132 degrees?

This can be solved using the cosine rule to find the length of side EF, and the sine rule to find angle E The cosine rule is: a² = b² + c² - 2bc cos A we have: A = G = 132° a = EF b = EG = 77 inches c = FG = 89 inches (the assignment of b and c doesn't matter as they are the two sides of the angle A and are interchangeable for the cosine rule), giving: EF² = 77² + 89² - 2×77×89×cos 132° → EF = √(77² + 89² - 2×77×89×cos 132°) The sine rule is: (sin A)/a = (sin B)/b = (sin C)/C we have: A = G = 132° a = EF = √(77² + 89² - 2×77×89×cos 132°) inches (found above) C = E c = FG = 89 inches → (sin 132°)/√(77² + 89² - 2×77×89×cos 132°) in = (sin E)/89 in → sin E = (89 sin 132°)/√(77² + 89² - 2×77×89×cos 132°) → E = arc sin((89 sin 132°)/√(77² + 89² - 2×77×89×cos 132°)) → E ≈ 25.8° → E ≈ 26° to the nearest degree


What is the cos of 89 degrees rounded to the nearest hundredth?

89.00


What is the square root of 356?

Go 89 units of distance in any fixed direction. Turn 90 degrees and go 89 units of distance. Turn 90 degrees in the same "wise" (clockwise or anticlockwise as before) and go 89 units of distance. Turn 90 degrees in the same "wise" (clock or anticlock) and go 89 units of distance.You will have returned to your starting point and you will have travelled along a square route whose distance was 356 units of length.
