3|-4-(-1)|+|2-3|=10
Final answer: 10
Answer:
Step-by-step explanation:
Given:
In Δ ABC
m∠C= 90°
For the triangle ABC we can apply trigonometric ratio to find m∠A.
We have:
Substituting values of side BC and AC
Taking inverse tan to get m∠A.
∴
AB can be found out using Pythagorean theorem:
AB being the hypotenuse can be written as
Substituting values of side BC and AC
Taking square roots both sides:
∴
The sum is the total of two numbers. For example, the sum of 2 and 3 is 5
Answer:
19.24 cm
Step-by-step explanation:
Square the outsides of the triangle. 8 squared is 64 and 5 squared is 25.
A^2+B^2=C^2
c^2 is always the diagonal line.
a^2=25
c^2=64
Subtract 25 from 64 to find b^2
64-25= 39
Add all three together to get your perimeter.
The square root of 64 is 8, the square root of 25 is 5 and the square root of 39 is 6.24. Add 8, 5 and 6.24 together and you get the perimeter.
5+8+6.24= 19.24
