I need your help (circle theorem question).

Mathematics
1 answer:
bixtya [17]2 years ago

Answer:

b = 108

c = 72

Step-by-step explanation:

The triangle formed by the two tangents is an isosceles triangle.

180 - 72 = 108

108/2 = 54

The other two angles in the triangle are equal to 54 degrees.

A tangent always meets the radius line at a right angle. Therefore, the radius line (between b and c) meets the tangent at 90 degrees.

90 - 54 = 36

Therefore the other two angles of 'b' triangle are equal to 36 degrees.

36 x 2 = 72

180 - 72 = 108

b = 108

And therefore b is equal to 108 degrees.

b + c = 180 (because a straight line is always equal to 180 degrees)

180 - 108 = 72

So c = 72

a recipe for 1 loaf of bread calls for 2 cups of flour, 12 tablespoons of water, and 1 teaspoon of salt. The recipe can be scale
natulia [17]

Answer:

Step-by-step explanation:

A recipe for 1 loaf of bread calls for 2 cups of flour, 12 tablespoons of water and 1 teaspoon of salt.

Therefore, if we add 2 loaves of bread then double of ingredients will be required for the recipe.

In the same way if 4 loaves of bread have been added, 4 times ingredients will be required.

If 3 cups of flour are added then 3 times of other ingredients will be required.

So the table will be,

Number of loaves   Cups of flour   Tablespoons of water    Teaspoons of salt

         1                             2                        12                                1

         2                             4                       24                                2

         4                             8                       48                                4

         3                             6                       36                                3

Describe all the positive integers that would make [(1/2|4] less than (1/2)7
Zielflug [23.3K]

Answer:

The only positive integers would be anything less than 3. So 1 or 2 would work

Step-by-step explanation:

If something that is already being raised to a power, gets raised to another power, those powers add up. So if it were (\frac{1}{2} ^{2} )^{2}, the exponents would add which would make it (\frac{1}{2}^{4} ).

In the case of your question, if 'n' was 2 it would be to the power of 6 making it less than to the power of. 1 could also work

notsponge [240]

This is solved by breaking the equasion down.

2 { 5 [12 + 5 (500 - 100) + 399 ]}

2 { 5 [12 + 5 (400) + 399]}

2 { 5 [12 + 2000 + 399]}

2 { 5 [2411]}
