Answer:
c. /pi/2
Step-by-step explanation:
Hey there!
Solve using pythagoras theorem (it's given that is triangle is right angled. Pythagoras theorem only works in the case of right triangles) ⇨ Hypotenuse² = Base² + Altitude ²
Here,
Base = 9 mm
Hypotenuse = 15 mm
Altitude = b
Hypotenuse² = Base² + Altitude ²
15² = 9² + b²
225 = 81 + b²
225 - 81 = b²
144 = b²
√144 = b
<u>1</u><u>2</u><u> </u><u>mm </u>= b
Hope it helps ya!
Answer: Only one.
Step-by-step explanation:
Let Δ ABC be a right isosceles triangle with two sides are 4 inches and the angle between them is 90°.
Then all the triangles with same measurement will be congruent to Δ ABC by SAS congruency criteria .
Therefore, there is only one triangle possible for the given measurement.
- <em>The </em><em>SAS postulate </em><em>says that if two sides and the included angle of a triangle are congruent to two sides and the included angle of another triangle, then the two triangles are congruent.

Answer:
41 miles per hour
Step-by-step explanation:
This is a fraction equal to
41 miles ÷ 1 gallon
We want a unit rate where
1 is in the denominator,
so we divide top and bottom by 1
41 miles ÷ 1
1 gallon ÷ 1
= 41 miles per gallon
I hope this works
