Question

Help me guys please (Step by step explanation need)

Answer 1

Answer:

100°

Step-by-step explanation:

To find the total interior angles of any polygon, the formula is (n-2) x 180.

So 5-2= 3

3 x 180 = 540

Straight line PTU adds up to 180°

180 - 85 = 95

95 + 125 + 130 + 90 = 440

550 - 440 = 100

Hope this helps!

Answer 2

$\huge\underline\mathfrak{Answer}$



100°


$\huge\underline\mathfrak{Solution}$


$\textbf{Some Important point about Pantagon}$


sum of all angle of a Pantagon is =540°


$\huge\underline\mathfrak{Figure}$


Look in attachment


put some construction


$\textbf{Step.1}$


$\angle{UTP}$=180°

(straight angle)


so, $\angle{UTL}$+$\angle{LTP}$

=180°


=> $\angle{UTL}$+85°=180°


=> $\angle{UTL}$=95°



so, now using Pantagon angle sum Properties


x°+90°+125°+130°+95°=540°


x°+440°=540°

x°=100°
