Answer:
Step-by-step explanation:
If M s the mid point of the line XY, then XM+MY = XY and XM= MY
Given
XM = 2x+7
MY = 8x-23
Since XM = XY, then;
2x+7 = 8x - 23
2x-8x = -23-7
-6x = -30
x = -30/-6
x = 5
Get XM
XM = 2x+7
XM = 2(5)+7
XM = 10+7
XM = 17
Get MY:
MY = 8x-23
MY = 8(5)-23
MY = 40-23
MY = 17
Since XY = XM+MY
XY = 17+17
XY = 34
6 · 45 =
6 · (40 + 5) =
6 · 40 + 6 · 5 =
C. 6 · 40 + 6 · 5
Answer:
a. 28˚
b. 76˚
c. 104˚
d. 56˚
Step-by-step explanation
a. because angle between tangent and chord is equal to the angle(s) in alternate segment.
b. because angles in triangles add up to 180˚, 180-28=152 and because isosceles triangle, 152/2=76˚
c. because angles in triangles add up to 180˚ and opposite angles in a cyclic quadrilateral add up to 180˚, 31+76=107, 180-107=73, 73-28=45, angles in triangle so 180-(31+45)=104˚
d. 28*2=56˚ because angles at circumference are half angles at centre
