Question

if c is the hypotenus find the measure, a=?,b= 20, c= 29​

Answer 1

Step-by-step explanation:

given:a=?

b=2

c=29

what we have to find=c(hypotenues)

hypotenuse^2=base^2+height

^2

c^2=a^2+b^2

29^2=a^2+20^2

841=a^2+400

a^2=400-841

a^2=-441

a=√441

a=21

therefore,the answer is a=21

Answer 2

Given:

c = 29 (hypotenuse)

b = 20

To find:

The value of a.

Here we will use Pythagoras theorem.

$H^{2}=P^{2}+B^{2}$  [Here H stands for Hypotenuse, P for Perpendicular and B for Base]

⭐Let's take 20 as the base.

$c^{2}=a^{2}+b^{2}$

$29^{2}=a^{2}+20^{2}$

$29^{2} -20^{2}=a^{2}$

841-400 = $a^{2}$

441 = $a^{2}$

$\sqrt{441}=a$

21 = a

Answer:

Value of a is 21.

Hypotenuse ⇒ c = 29

Perpendicular ⇒ a = 21

Base ⇒ b = 20
