Is asking on using two angles and the side joining them, like in the picture below, notice the two blue angles and the red side joining them.
the only thing is that, you have to use angles, and a side, that will be feasible to produce a triangle, meaning, the other two sides will at some point meet and close off the triangle.
Answer:
221
Step-by-step explanation:
use bidmas (brackets,indices, division,multiplication,addition,substraction)
Answer:
y=2
y=0
Step-by-step explanation:
Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation :
7*y-1-(3*y^2+y-1)=0
(7y - 1) - ((3y2 + y) - 1) = 0 3.1 Pull out like factors :
6y - 3y2 = -3y • (y - 2)
Answer:
Measure of each angle is 90 degree.
Step-by-step explanation:
Given : If two consecutive angles of a parallelogram are congruent.
To find the measure of each angle:
There are 6 important properties of parallelograms:
- Opposite sides are congruent.
- Opposite angles are congruent
- Consecutive angles are supplementary.
- If one of the angle is right angle, then all angles are right.
- Diagonals of a parallelogram bisect each other
- Also, each diagonal of a parallelogram separates it into two congruent.
let A and D be two consecutive angle.
then, by the given condition
......[1]
From the property of parallelogram:
Consecutive angles are supplementary
Then;
From equation [1];
Combine like terms :
Divide both sides by 2 we get;
Simplify:
From the given property of parallelogram : if one of the angle is right, then all the angles in the parallelogram are right angle.
∴
Therefore, the measure of each angle is
