Answer 1

Step-by-step explanation:

hey there here is your answer ....

From the figure we can say that angle (2x+15)° is equal to corresponding angle of angle (3x-10)° [since vertically opposite angles ]

therefore we have

2x+15 = 3x-10

\begin{gathered}2x + 15 = 3x - 10 \\ 15 + 10 = 3x - 2x \\ 25 = x\end{gathered}

2x+15=3x−10

15+10=3x−2x

25=x

therefore x = 25

hope it helps..☺️

Answer 2

$\huge\bold{\gray{\sf{Answer:}}}$

Explanation:

$3x - 10 + 2x + 15 = 180(angle \: on \: the \: same \: side \: of \: transversal)$

$= > 5x + 5 = 180$

$= > 5x = 175$

$\bold{ = > x = \frac{175}{5} = 35°}$

Now finding angle :-

$3x - 10 = 105 - 10 = 95°$

$2x + 15 = 2 \times 35 + 15 = 85°$

Now adding both :-

$\bold{95°+ 85° = 180°}$

You can also check by :-

∠A+95=180°

∠A=85°

∠B=75°

∠C=105°

Now , adding all angles

$= > 85° +7 5° + 105° + 95° = 360°$(complete angle revolution)
