<span>D. Zahra can make more than one triangle with these angle measures.
(Infinite similar triangles)</span>

Answer:

OPtion A Zahra cannot make a triangle with these angle measures.

Step-by-step explanation:

To draw a triangle we must have atleast 3 independent dimensions

Here only 2 are given as third angle depends on first 2.

Hence Zahra cannot make a triangle with these angle measures.

If at all she wants to draw she has to assume some side atleast one side and make triangle

But this is infinite as she can do for any size of her choice.

A valley in California has an elevation of feet below sea level. A valley in Arizona has an elevation lower than the one in Cali
Galina-37 [17]

The valley in California has an elevation of feet "below sea level".
Below sea level means below 0 feet, so it'd have -5 feet

The one in Arizona would be lower than it, so the elevation will definitely be -9 feet

1) Area = leg(1) * leg(2) * .5 = 15 * 36 * .5 = 270

Perimeter = leg(1) + leg(2) + hypotenuse = 15 + 36 + 39 = 90

2) Area = leg(1) * leg(2) = 20 * 80 = 1600

3) Median (divides it in 1/2)

4) Both (divides it in 1/2 and makes a 90 degree angle w/ base)

5) Altitude (makes 90 degree angle w/ base)

6)sqrt(30^2 + 16^2) = sqrt( 900 + 256) = sqrt(1156) = 34

7) sqrt(24^2 + 18^2) = sqrt( 576 + 324) = sqrt(900) = 30

8) sqrt(40^2 + 96^2) = sqrt(1600 + 9216) = sqrt(10816) = 104

9) sqrt(150^2 - 90^2) = sqrt(22500 - 8100) = sqrt(14400) = 120

10) sqrt(35^2 - 25^2) = sqrt(1225 - 625) = sqrt(600) = 10sqrt(6), approx. 24.5
