We know that
Inner angle,<span> has its center at an inner point of the circle.
</span><span>The measure of the interior angle is the half-summit of the arcs that comprise it and its opposite.
</span>so
m ∠DEC=[Arc DC+<span>Arc AB]/2------> [150+90]/2-----> 120</span>°
the answer is
120°
Answer:
125
Step-by-step explanation:
In ΔPTO we are given that
∠PTO = 90° (indicated by the right angle)
and ∠TPO = 35°
And we need to find the exterior angle (∠TOB)
If you didn't know this is the rule about exterior angles
Exterior angles of a triangle are equal to the sum of the opposite interior angles of a triangle
So more specifically for this problem
∠TOB = ∠PTO + ∠TPO
Now that we have created an equation we want to plug in the values that we are given
∠TOB = 90 + 35
90 + 35 = 125
Therefore the answer is 125
Answer:
x=6,y= 7
Step-by-step explanation:
-6x +7y= 13
-6x+8y=20
-y = -7
divide through by -1
y =7
sub y= 7 in equation 1
then x= 6
Answer: 7 & 10
Step-by-step explanation:
7+10=17
10-7=3
