Please answer question ASAP! Use the triangle below to determine which of the following statements are true. (The answer choices

vagabundo [1.1K]

Choice A is true. This is the Pythagorean identity. One of the most fundamental trig identities you should memorize.

Choice B is false. Let A = 60 and B = 30 and you'll see the left hand side turn into 0.5 while the right hand side turn into -0.5

Choice C is true. This is a variation of the identity tan^2+1 = sec^2 (just subtract tan^2 from both sides)

Choice D is true as this is a more complicated variation of 1+tan^2 = sec^2

Which of the following shows 9x^2y - 4x + 3y^3x - 2y^2 written in standard form? A. 9x2y - 4x + 3y3x - 2y2 B. 3y3x - 2y2 + 9x2y

nlexa [21]

D. $3 y^{3}x+9 x^{2} y-2 y^{2} -4x$

Take each term and find the degree of the term and then put them in order from highest to lowest:
$y^{3}x=3+1=4$
$x^{2} y=2+1=3$
$y^{2}=2$
x=1

Remember a letter without an exponent is assumed to be a 1.

Hope that helps.

Given: QR I PT and ZQPR = ZSTR

Rina8888 [55]

Answer:

$\triangle PQR \sim \triangle TSR$

Step-by-step explanation:

Given :

QR⊥PT

$\angle QPR = \angle STR$

To Prove : $\triangle PQR \sim \triangle TSR$

Solution:

Statements Reasons

QR⊥PT Given

∠QRP and ∠SRT are right angles Def of perpendicular

∠QPR≅∠STR Given

∠QRP = ∠SRT All right angles are equal

ΔPQR≈ΔTSR AA similarity

Hence $\triangle PQR \sim \triangle TSR$
