Answer:
10
Step-by-step explanation:
The question lacks appropriate diagram. Find the diagram attached below.
From the isosceles triangle shown, we can see that it is made up of two right angled triangle.
Using the Pythagoras theorem to solve for the adjacent side of both right angled triangles we will have;
From the formula:
Hyp² = Opp²+Adj²
Adj² = Hyp² - Opp²
The hypotenuse and the opposite of both triangle is equal. Hence their adjacent side will also be equal.
Given Hypotenuse = √74
Opposite = 7
Adj² = Hyp²-Opp²
Adj² = (√74)² - 7²
Adj² = 74-49
Adj² = 25
Adj = √25
Adj = 5
The adjacent of both sides are equal
x = 2 × Adjacent side
x = 2(5)
x = 10
Hence the value of x in the triangle below is 10
Answer:
y= -x-9 because you have to find the negative reciprocal of the slope of the original line and then use the point slope formula y-y1=m(x-x1) to find the perpendicular line
Answer:
32 years
Step-by-step explanation:
8x12 because there are 12 inches in a foot
8x12=96
96/3
96/3=32
Angle MNO is 90, it’s just the top right corner
Answer:
m=-2
Step-by-step explanation:
7(m+5)=21
m+5=21/7
m+5=3
m=3-5
m=-2
