In the diagram below, mpr = 140 and mqs = 106. What is the measure of ptr?

choli [55]

Answer:

Option B

$m\angle PTR=123^o$

Step-by-step explanation:

we know that

The measure of the interior angle is the semi-sum of the arcs comprising it and its opposite

$m\angle PTR=\frac{1}{2}[arc\ PR+arc\ QS]$

substitute the given values

$m\angle PTR=\frac{1}{2}[140^o+106^o]$

$m\angle PTR=123^o$

Please help me find large & smaller angle

Dennis_Churaev [7]

If one angle is 9 times the other angle, and they're complementary, you can set up an equation.

90 = x + 9x

x is the smaller angle. When you solve for x, you get 9.

So, the large angle is 81°, and the smaller angle is 9°.

Hope this helped!! xx

Can someone check my answer?

The measure of EC is 1 ft.

Solution:

Given data:

AD = 8 ft, DB = 2 ft, AE = 4 ft

To find the measure of EC:

Using triangle proportionality theorem,

<em>If a line is parallel to one side of a triangle intersects the other two sides, then it divides the two side proportionally.</em>

$$\frac{AD}{DB} =\frac{AE}{EC}$

$$\frac{8}{2} =\frac{4}{EC}$

Do cross multiplication.

$8EC=2\times 4$

8 EC = 8

Divide by 8 on both side of the equation, we get

EC = 1

EC = 1 ft

Hence the measure of EC is 1 ft.

Ian is going to water his plants is it reasonable to say he will fill the watering can with 3 liters of water explain

sveta [45]

This is possible for a smaller watering can. 3 liters is about 3/4 of a gallon (imagine a jug of milk).

It is equivalent to 3000 ml, which would also be 100 ounces of water.(5 -20 oz bottles of water).
