Answer:
i need help with this too
Step-by-step explanation:
<h2><u>Solution:</u> </h2>
<u>Steps of Statement: </u>We will solve right Angled ∆ RST. We will use Trigonometric Ratio to solve this Question.
<u>Now, In ∆ RST , Where angle C is 90° and angle D is 60° </u>
∠RTS = 60°
So, Sin 60° = RS / RT
☛ √3/2 = 2√3 / RT
☛ RT = 4
<u>Now, Let's Solve Right angled ∆ QRT </u>
tan 45° = QR / RT
☛ 1 = x / 4
☛ x = 4
<h2>Therefore, Required Value of x is <u>4</u>. </h2>
<span>2x^3 + 10x^2 + 4x + 20
= 2(x^3 + 5x^2 + 2x + 10)
= 2[x^2(x + 5) + 2(x + 5)]
= 2[(x+5)</span>(x^2 + 2)<span>]
answer
</span>2[(x + 5)(x^2 + 2)]
Answer:
supplementary
Step-by-step explanation:
Consecutive angles in a parallelogram sum to 180°
That is they are supplementary.
