Find the value of xm<2= 10x + 10​

Mathematics

3 0

Answer:  x = 12

<u>Step-by-step explanation:</u>

a) Linear Pair: 110° + ∠a = 180°  -->    ∠a = 70°

b) congruent sides implies congruent angles  --> ∠b = 70°

c) Triangle Sum Theorem: ∠a + ∠b + ∠c = 180

                                         70° + 70° + ∠c = 180°

                                                            ∠c = 40°

d) Complimentary Angles: ∠c + ∠d = 90°

                                          40° + ∠d = 90°

                                                   ∠d = 50°

∠2) Linear Pair: ∠d + ∠2 = 180°

                         50° + ∠2 = 180°

                                  ∠2 = 130°

x) m∠2 = 130°

   10x + 10 = 130°

   10x        = 120

       x        = 12

Prove the identity sin4x=2sin2xcos2x
Musya8 [376]
There is a trig identity called the sum of 2 angles for sin its<span>
sin(a+b)=sin(a)cos(b)+cos(a)(sin(b)
</span>
You will need to use it. So in your question split the 4x in 2 equal parts 2x and 2x
 <span>
</span><span>sin(4x)=sin(2x+2x)

</span>Now using the expansion above you will get

<span>sin(2x+2x)=sin(2x)×cos(2x)+cos(2x)×sin(2x)

</span>And it will simplify to 

<span><span>2sin(2x)cos(2x)

I hope this helps you! Good luck :)</span></span>
