Question

Someone helpp !! I don’t understand this at all

Answer 1

Answer:

∠AB=9

Step-by-step explanation:

the pyagrothyes therom= $a^{2}$+$b^{2}$=$c^{2}$

to find ∠AB we need to find the height of the triangle.

replace the variables:

$a^{2}$+$6^{2}$=$9^{2}$

=$9^{2}$-$6^{2}$=$a^{2}$

simplify:

81-36=$\sqrt{45}$

now we solve for ∠AB

replace the variables:

$6^{2}$+$\sqrt{45}$=$c^{2}$

simplify:

36+45=$\sqrt{81}$

$\sqrt{81}$=9

I hope this helps you!!

have a nice day!!
