Given:
ABC is an isosceles triangle in which AC =BC.
D and E are points on BC and AC such that CE=CD.
To prove:
Triangle ACD and BCE are congruent.
Solution:
In triangle ACD and BCE,
(Given)
(Common angle)
(Given)
In triangles ACD and BCE two corresponding sides and one included angle are congruent. So, the triangles are congruent by SAS congruence postulate.
(SAS congruence postulate)
Hence proved.
Answer
h^-1(x)= x+43
Explanation
h(x)=x-43
Use substitution
y=x-43
Interchange the variables
x=y-43
Swap the sides
y-43=x
Move the constant to the right
y=x+43
Use substitution
h^-1(x)=x+43
Answer:
c
Step-by-step explanation:
Any ride takes $2.00 and one mile takes $0.20.
Cost = $0.20 + $2.00
Cost = $2.20
The length of the side = <span>The length of the arc intercepted by the central
<span>angle
</span></span>∴ length = Θ r
where Θ = <span>central<span> angle in radians
and r = radius
∴ </span></span><span>Θ = 70° = 70 * π /180
</span><span>r = 13 in.
∴ </span>length = <span>(70 * π /180) * 13 ≈ 15.88 in.
</span>
Answer:
The newborn grew by forty-five percent.
Step-by-step explanation:
(16-11)/11 * 100
= 5 / 11 * 100
= 0.454545... * 100
≅45 %
