Check the picture below.
the "red" pair of sides are congruent, notice, both are 3 and 5 units in length respectively.
Answer:
Therefore,

The Measurement of AB is 16.25 units.
Step-by-step explanation:
In Right Angle Triangle ABC
m∠C=90°
AC = 10.01 .....(Adjacent Side to angle A)
m∠A=52°
cos 52 ≈ 0.616
To Find:
AB = ? (Hypotenuse)
Solution:
In Right Angle Triangle ABC, Cosine Identity,

Substituting the values we get

But cos 52 ≈ 0.616 ....Given

Therefore,

The Measurement of AB is 16.25 units.
Easy, first turn the factions into deciamls, then so 1.16-7.8=6.64. So, 6.64
Answer:
1)24 2)36 3)240
Step-by-step explanation:
1) area of triangle = 1/2b*h so 7*4=28 28/2=14
therefore area =24
2)9*4=36
3)15*16=240
