Answer:
10
Step-by-step explanation:
Square = 2 x 2 = 4
The Small triangle is half of the square so 4 divided by 2 is 2.
The big triangle 4 x 2 = 8 divided by 2 is 4.
So,
4 + 2 + 4 = 10
Answer:
The answer is d
Step-by-step explanation:
Because all angles in parallelogram are the same
AC is a tangent so by definition, it touches the circle at exactly one point (point C) and forms a right angle at the tangency point. So angle ACO is 90 degrees
The remaining angle OAC must be 45 degrees because we need to have all three angles add to 180
45+45+90 = 90+90 = 180
Alternatively you can solve algebraically like so
(angle OAC) + (angle OCA) + (angle COA) = 180
(angle OAC) + (90 degrees) + (45 degrees) = 180
(angle OAC) + 90+45 = 180
(angle OAC) + 135 = 180
(angle OAC) + 135 - 135 = 180 - 135
angle OAC = 45 degrees
Side Note: Triangle OCA is an isosceles right triangle. It is of the template 45-45-90.
