Answer:
The larger angle is 54°
Step-by-step explanation:
Given
Let the angles be: θ and α where
θ > α
Sum = 72
α : θ = 1 : 3
Required
Determine the larger angle
First, we get the proportion of the larger angle (from the ratio)
The sum of the ratio is 1 + 3 = 4
So, the proportion of the larger angle is ¾.
Its value is then calculated as:.
θ = Proportion * Sum
θ = ¾ * 72°
θ = 3 * 18°
θ = 54°
Answer:
The answer is x=9 and/or x = -12
Step-by-step explanation:
This is a quadratic formula meaning that you must take the a value (1) b value (3) and the c value (108) and plug it into the quadratic formula.
which simplifies to -3 add or subtract the sqrt of 441 divided by two.
The answer is 217 with a remainder of 20.
explanation is in the picture.
Answer:
BR bisects the angle ABC, and is called the bisector of angle ABC.
Step-by-step explanation:
Step 1: Draw an arc with B as the centre to cut the arms, BA and BC, of the angle at P and Q respectively.
Step 2: Using the same radius, draw an arc centred at P.
Step 3: With centre Q and using the same radius, draw an arc to cut the arc in Step 2 at R.
Step 4: Join, B, the vertex of the angle to the point R.
