Answer:

x ≈ 35.6

Step-by-step explanation:

Using the cosine ratio in the right triangle

cos16° = \frac{adjacent}{hypotenuse} = \frac{x}{37} ( multiply both sides by 37 )

37 × cos16° = x , then

x ≈ 35.6 ( to the nearest tenth )

(6u^2+5u^2v^2−3uv^2)−(4u^4+5u^2^v^2−5uv)
Aleksandr [31]

Answer:

-4u^{4}+6u^{2}-5uv-3uv^{2}

Step-by-step explanation:

When subtracting polynomials, first start with distributing the negative sign to the second polynomial:

6u^{2} + 5u^{2} v^{2}-3uv^{2}-4u^{4}-5u^{2}v^{2}+5uv

Simplify by combining like terms:

-4u^{4}+6u^{2}-5uv-3uv^{2}

Yes

sum of angle = 180°

First diagram

R+D+E=180°

110°+28°+E=180°

138°+E=180°

E=180°-138°

E=42°

Second diagram

T+V+A=180°

T+28°+42°=180°

T+70°=180°

T=180°-70°

T=110°

you divide 5x by 5 and seven by five so your x= that answer

then you put that number into the x in the second equtaion

then you subtract that number after multiplying the 6 by the number x equals

then you divide 2y by 2 and 22 by 2 and thats your y value
