Question

please help me am confused it's an emergency ​

Answer 1

Brainly is for clearing doubs not for aolving question paper

Answer 2

Step-by-step explanation:

2.) tanB=9/20

   tanB=0.45

   B=tan⁻¹0.45

   B=24.23°

3).sinC=8/10

  sinC=0.8

  C=sin⁻¹0.8

  C=53.13°

4.)sin78=10/x          &                   tan78=10/w

  0.97=10/x                                 4.71=10/w

  0.97x=10                                  4.71w=10

  x=10/0.97                                  w=10/4.71

  x=10.31                                     w=2.13

1.)5²+4²=y²

 25+16=y²

 41=y²

  y=6.4

        hope it helps mark as brilliant please.
