The rate of change for both functions is 2.
Answer:
x=37°
y=6
Step-by-step explanation:
(ASSUMING BD is a perpendicular bisector of AC, otherwise answers maybe be wrong)
Consider the triangle ABC:
AB is the same length as BC (marked), meaning ABC is an isosceles triangle.
Since ABC is isosceles, ∠BAC=∠BCA=53
All angles in a triangle add up to 180:
180=∠ABC + ∠BAC + ∠BCA
180= ∠ABC + 53 +53
∠ABC = 180 - 106
∠ABC = 74
Assuming BD bisects ∠ABC perfectly, x is half of ∠ABC.
x=74/2=37
If BD bisects AC perfectly, AD=DC=y=6
Answer:
<em>£</em><em>1</em><em>9</em>
Step-by-step explanation:
Cheryl = 7 + 5 = £12
this means ova and eva also have £12 at the end
EVA'S ORIGINAL AMOUNT : X -7 =12
X = £19
Lets check
47 times 7 is not equal to 315
47 times 5 =235
47 times 9 is not equal to 235
alishas speed is 47 mph
Answer:
They are both right angles and they both have a measure of 28°.
Step-by-step explanation:
angle A and angle B are both right angles (90°), and they both have a side measuring 28°. For the missing sides of both the measurement should be 62°.
