Answer:
64°
Step-by-step explanation:
Both triangles represent a right angle by the small box in the angle.
Right angles = 90°
Since the triangles are congruent, then they would have the same measurements in their angles an sides. All triangles also have a sum of 180°. So, we can just subtract (26 + 90) from 180 to get the third angle.
180 - (26 + 90)
180 - 116
64
So, the m∠KLM is 64°.
7/8 is already in the simplest form, so just rewrite it on the line.
It seems like a trick question but you actually only need to factor it once
The shorter leg is 21cm, longer leg is 28 cm and hypotenuse is 35cm.
Step-by-step explanation:
Let,
The longer leg = x
The shorter leg = x-7
Hypotenuse = x+7
Using Pythagoras theorem;
Either,
x= 0
Or,
x-28=0 =>x=28
As length cannot be zero, therefore,
Longer side = 28cm
Shorter side = x-7 = 28-7 = 21cm
Hypotenuse = x+7 = 28+7 = 35cm
The shorter leg is 21cm, longer leg is 28 cm and hypotenuse is 35cm.
