Since QP and QB are equal the triangle PQB the angles:
The last angle can be found by adding all the internal angles and making it equal to 180 degrees.
The angle BQP and the angle AQP are suplementary, this means that their sum is equal to 180 degrees. So we have:
Since the sides AP and PQ are equal, then the angle PAQ is equal to AQP.
To find the last angle on that triangle we can add all the internal angles and make it to 180 degrees.
The angle APC is suplementary with the sum of the angles APQ and BPQ. So we have:
The sides AP and AC are equal, therefore the angles APC and ACP are also equal.
Then we can find the last angle on that triangle.
The angle CAB is equal to the sum of CAP and PAQ. So we have:
Since the sides AB and BC are equal, then the angles ACB and CAB must also be equal. We can find the value of x with this.
The value of x is 180/7
Answer:
16n
Step-by-step explanation:
5n+11n=16n because 5+11 =16 and you just multiply each number by n.
Answer:
Step-by-step explanation:
To find the length of an isosceles triangle, you know that the angles of the triangle are 45-45-90, so let's use that triangle theorem.
Therefore, the length of the hypotenuse (BD) is , and x is equal to 8 (length of BC).
x=8
Therefore, would be the length of side BD.
Answer:
x = 30°
Step-by-step explanation:
the small triangle is equilateral
That means that side with angle x that shares the same side with the other triangle is also 40
so its isosceles
in the equilateral, all angles measure 60
so 180 -60 = 120
180 - 120 = 60
60/2 = 30
