Question

figure shows kite ABCD and the measure of marked angles find a and b ​

Answer 1

Step-by-step explanation:

here opposite angle are 10degree

that is

$< a + < c = 180 \\ < b + < d = 180$

by taking above trangle sum

2a+30+3b-10+<B=180

2a+3b+<B=160

by taking below triangle sum

a+50+b+20+<D=180

a+b+<D=110

by adding both

3a+4b+<B+<D=270

we know sum of angle b, d =180

substitute it

3a+4b+180=270

3a+4b=90
