Answer:

See below.

Step-by-step explanation:

Recall that the biggest angle will always be opposite from the biggest side.

IT is opposite from Angle S, which we can figure out to be 180-108-25=47.

SI is opposite from Angle T, which is 41.

ST is opposite from Angle I (the whole thing). Just from looking at it, we know that it is the biggest angle. If we want to figure it out, Angle I is 180-41-72+25=92.

The smallest side is SI, then IT, then ST.

The correct order is: SI, IT, and ST.

Y=109x y=79x+2506 can some one solve both equations and a graph would be helpful plz

Amiraneli [1.4K]

Answer:

x ≈ 83.533

y = 9105.13

Step-by-step explanation:

Step 1: Substitution

109x = 79x + 2506

30x = 2506

x = 83.533

Step 2: Plug x in

y = 109(83.533)

y = 9105.13

Prove that if xy > 0, then either x > 0 and y > 0 or x < 0 and y < 0

Rufina [12.5K]

The rule of product states that:

$(+) \cdot (+) = (+)$
$(+) \cdot (-) = (-)$
$(-) \cdot (+) = (-)$
$(-) \cdot (-) = (+)$

So, a product is positive if and only if both factors have the same sign, and is negative if only if the factors have opposite sign.

How do you solve: secx=-5/2, tanx<0 Find all six trig functions

Brut [27]

Answer:

sec theta = (sqrt24/5) cos theta = -2/5 tan theta = (-[sqrt 21]/2) sec theta = 5/2 csc theta = (5sqrt21)/21 cot theta = (-2sqrt21)/21

Step-by-step explanation:

During the problem, secx = -5/2, we can assume that as cos = -2/5. -2 = x. 5 = r. find for Y with: x^2+y^2=r^2. After that, plug in for the variables and you get all the answers. Rationalize the square roots, don't forget.
