Given :

ZC = 90°

CD is the altitude to AB.

$\angle$ A = 65°.

To find :

the angles in △CBD and △CAD if m∠A = 65°

Solution :

In Right angle △ABC,

we have,

=> ACB = 90°

=> $\angle$ CAB = 65°.

So,

=> $\angle$ ACB + $\angle$ CAB+ $\angle$ ZCBA = 180° (By angle sum Property.)

=> 90° + 65° + $\angle$ CBA = 180°

=> 155° + $\angle$ CBA = 180°

=> $\angle$ CBA = 180° - 155°

=> $\angle$ CBA = 25°.

In △CDB,

=> CD is the altitude to AB.

So,

=> $\angle$ CDB = 90°

=> $\angle$ CBD = $\angle$ CBA = 25°.

So,

=> $\angle$ CBD + $\angle$ DCB = 180° (Angle sum Property.)

=> 90° +25° + $\angle$ DCB = 180°

=> 115° + $\angle$ DCB = 180°

=> $\angle$ DCB = 180° - 115°

=> $\angle$ DCB = 65°.

Now, in △ADC,

=> CD is the altitude to AB.

So,

=> $\angle$ ADC = 90°

=> $\angle$ CAD = $\angle$ CAB = 65°.

So,

=> $\angle$ ADC + $\angle$ CAD + $\angle$ DCA = 180° (Angle sum Property.)

=> 90° + 65° + $\angle$ DCA = 180°

=> 155° + $\angle$ DCA = 180°

=> $\angle$ DCA = 180° - 155°

=> $\angle$ DCA = 25°

Hence, we get,

$\angle$ DCA = 25°
$\angle$ DCB = 65°
$\angle$ CDB = 90°
$\angle$ ACD = 25°
$\angle$ ADC = 90°.

The diet will include <u>123.75 </u>daily grams of protein

<h3>Further explanation</h3>

One variable linear equation is an equation that has a variable and the exponent number is one.

Can be stated in the form:

$\large{\boxed{\bold{ax=b}}$

ax + b = c, where a, b, and c are constants, x is a variable

We complete the task :

A nutritionist planning a diet for a football player wants him to consume 3,500 Calories and 725 grams of food daily. Calories from fat and protein will be 45% of the total Calories. There are 4, 4, and 9 Calories per gram for protein, carbohydrates, and fat, respectively. How many daily grams of protein will the diet include?

243.75
481.25
123.75
120

Calories from fat and protein will be 45% (0.45) of the total Calories

Calories from fat and protein = 0.45 x 3500 = 1575 calories

Calories from carbohydrates = 3500 - 1575 = 1925 calories

So mass for carbohydrates = 1925 : 4(4 calories/gram) = 481.25 grams

Then mass for fat and protein = 725 - 481.25 = 243.75 grams

We can make equation for fat and protein

1. 4 calories. mass of protein(p) + 9 calories . mass of fat(f) = 1575 calories

2. mass of protein(p) + mass of fat(f) = 243.75

we can simplify :

1. 4p+9f = 1575

2. p + f = 243.75 ⇒ f = 243.75 - p

we substitute equation 2 into equation 1 :

4p + 9(243.75-p) = 1575

4p + 2193.75-9p=1575

-5p = -618.75

p = 123.75

On January 1, Mindy’s automobile mileage reading was 19,496. On December 31, the reading was 39,835. To the nearest hundred mile

lys-0071 [83]

Well all you have to do is subtract 19,496 from 39,835. 39,835-19,496=20340 now you have to round to the nearest hundred. Your answer would be 20,300 miles

Answer:

-8y+12

Step-by-step explanation:

4(-2y +3)

you can distribute the 4

4 • -2y + 4 • 3

= -8y +12

because they are not like terms, you cannot do anything further.
