In ∆ABC the angle bisectors drawn from vertexes A and B intersect at point D. Find ∠ADB if:
icang [17]

Answer:

155°

Step-by-step explanation:

In Δ ABC, let A = x°

By Angle-sum property,

A + B + C = 180°

But, it is given that C = 130°

So, x + B + 130 = 180

B = 180 - 130 - x

B = 50 - x

Since AD and BD are internal bisectors of A and B,

∠ DAB = x/2 and

∠ DBA =

In Δ ADB, by angle-sum property,

∠ DBA + ∠ DAB +∠ ADB = 180°

+ ∠ ADB = 180°

25 + ∠ ADB = 180°

∠ ADB = 180 - 25 = 155°

Hence, ∠ ADB = 155°

The sum of two consecutive integers is at least 185. what is the smaller of the two integers? enter your answer in the box.
ss7ja [257]
Let us assume the first integer to be = x
Then
The second integer will be = x + 1
The sum of the two consecutive integers =185
Then
x + x + 1 = 185
2x + 1 = 185
2x = 184
x = 92
From the above deduction, we can easily conclude that the smallest of the two integers is 92. I hope that the answer has helped you.

The water has been on the stove y=9.5x+62.1 after how many minutes will the tempature be 138.1 F
kotegsom [21]

Answer:

After 8 minutes will the temperature be 138.1 F

Step-by-step explanation:

Given that:

The water has been on the stove y=9.5x+62.1      .....[1]

where

y represents the temperature in Fahrenheit(F)

x represents the time in minutes.

We have to find after how many minutes will the temperature be 138.1 F.

⇒y = 138.1 F

Substitute the given value in [1] to solve for x;

138.1=9.5x+62.1

Subtract 62.1 from both sides we get;

76=9.5x

Divide both sides by 9.5 we get;

8 = x

or

x = 8 minutes.

Therefore, after 8 minutes will the temperature be 138.1 F
