One angle of a triangle is 30° more than the smallest angle. The largest angle is the sum of the other angles. Find the measures

vladimir1956 [14]

Answer: $\boxed{30^{\circ}, 60^{\circ}, 90^{\circ}}$

Step-by-step explanation:

Let the smallest angle be x.

Then, the middle angle is x+30.

The largest angle is 2x+30.

Angles in a triangle add to 180 degrees, so:

$x+x+30+2x+30=180\\\\4x+60=180\\\\4x=120\\\\x=30$

So, the angles measure $\boxed{30^{\circ}, 60^{\circ}, 90^{\circ}}$

I need help lol I’m taking this test

Vera_Pavlovna [14]

Answer:

A) T = -1.

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

10t+4−2t=2−2(t+4)

10t+4+−2t=2+(−2)(t)+(−2)(4)(Distribute)

10t+4+−2t=2+−2t+−8

(10t+−2t)+(4)=(−2t)+(2+−8)(Combine Like Terms)

8t+4=−2t+−6

8t+4=−2t−6

Step 2: Add 2t to both sides.

8t+4+2t=−2t−6+2t

10t+4=−6

Step 3: Subtract 4 from both sides.

10t+4−4=−6−4

10t=−10

Step 4: Divide both sides by 10.

Hope this helps!

A test to determine whether a certain antibody is present is 99.1% effective. This means that the test will accurately come bac

avanturin [10]

Answer:

The probability that all the six people will test negative for the antibody is 0.9472.

The probability that the test comes back positive for at least one of the six people is 0.0528

Step-by-step explanation:

Consider the provided information.

probability that antibody is present will be effective is 99.1% and not present is 99.1% of the time.

Part (A)What is the probability that the test comes back negative for all six people? 

Let P(X)= P(Antibody not present)

We want test comes back negative for all six that means antibody is present for all six. Thus X=0

$P(X=0)=0.991\times0.991\times0.991\times0.991\times0.991\times0.991\\P(X=0)=0.9472$

The probability that all the six people will test negative for the antibody is 0.9472.

Part (B) What is the probability that the test comes back positive for at least one of the six people?

$P(X \geq1)=1-P(X=0)$

$P(X \geq1) = 1-0.9472$

$P(X \geq1) = 0.0528$

Hence, the probability that the test comes back positive for at least one of the six people is 0.0528
