The answer is C) m∠1 + m∠2 = 90
Explanation: So ∠1 is x and ∠2 is x-4
Basically you know than ∠3 is 90° ... And a straight line is 180° .. So technically we can just find out 180-90 is 90(the other angle 1 + 2).
To get 90° we'll add ∠1 and ∠2 in other ways, like technical thinking-
So you already know adding ∠1 and ∠2 is 90°. So ∠1 + ∠2 = 90°
In other words you can say m∠1 + m∠2 = 90
Answer: Ann = 67 Josh = 60 Claire = 30
Step-by-step explanation: You get the equation 5x+7 = 157. You get the equation because for example, Claire = x then josh = 2x and Ann = 2x + 7. You do all the math and boom! You get the answer :)
Answer:
3.14
Step-by-step explanation:
First find the circumference of the circle:
= Circumference.
= 
Find the ratio of the angle in relation to the entire circle:
is what we have. So:

Use the ratio and multiply the circumference to find the length:
= 
Round answer to the hundredth:
1 step: to draw a rectangle around triangle RST, you should
- draw points A(-1,-1), B(-1,3) and C(2,3);
- connect points A, B, C and T consecutively.
2 step: rectangle ABCT has length AB=4 units and width BC=3 units. Then
sq. un.
3 step:
sq. un.
sq. un.
sq. un.
4 step:
sq. un.
Answer: in step two you write dimensions of rectangle ABCT: length 4 units and width 3 units. Correct choice is B.
