Answer:
Step-by-step explanation:
You can set this up by reversing it.
(9+4)- (x/2)
(13)-(x/2)
(13)-(2x)
=11x
Answer: The triangles are congruent by HL (hypotenuse leg)
We have two right triangles. The tickmarks show the legs are congruent. The hypotenuses are congruent because they overlap perfectly. The hypotenuses are a shared common side. Using HL, we can prove the triangles to be congruent.
Side note: You could use the pythagorean theorem to find the measure of the third pair of sides, and that would lead to using SSS.
The answer for question 4:
a) 3(3n-1)=9n-3
b) 9n-3=96
9n=96+3
9n=99
n=11

Dogs do not lay eggs. Instead, they are classified as mammals and give birth to live young. ... Like all mammals, they have internal fertilization of their eggs. After estrus, a period, known as diestrus, occurs, whether the dog is pregnant or not
Answer:
9.2 yd
Step-by-step explanation:
Given,
hypotenuse(h)=10 yd
base(b)=4yd
perpendicular(p)=?
we have Pythagoras Theorem
h²=p²+b²
p²=h²-b²
p=(h²‐b²)½
=(10²-4²)½
=(100-16)½
=(84)½
=9.2
