Answer:

The angle of A is 80°

Step-by-step explanation:

Given that angle A lies on a straight line which is 180°. So in order to find A, you have to substract 100° from 180° :

∠A + 100° = 180°

∠A = 180° - 100°

∠A = 80°

What is the solution of....

mote1985 [20]

$\huge \mathscr{\blue {\underline {\red{\underline{Answer :-}}}}}$

$\bf \frac{5}{2} x - 7 = \frac{3}{4} x + 14$

$\bf \implies \: \frac{5}{2} x - \frac{3}{4} x = 14 + 7$

$\bf \implies \: \frac{10x - 3x}{4} = 14 + 7$

$\bf \implies \: \frac{7}{4} x = 21$

$\bf \implies \: 7x = 21 \times 4$

$\bf \implies \: x = \frac{21 \times 4}{7}$

$\bf \implies \: x = 3 \times 4$

$\bf \implies \: x = 12$
