Sever21 [200]3 years ago

Answer:

Step-by-step explanation:

a) The sum of the angles in a triangle is 180 degrees. This means that

Angle A + angle B + angle C = 180

Therefore,

3x + 28 + 5x + 52 + 2x - 10 = 180

Collecting like terms, it becomes

3x + 2x + 5x + 28 + 52 - 10 = 180

10x + 70 = 180

Subtracting 70 from both sides of the equation, It becomes

10x + 70 - 70 = 180 - 70

10x = 110

Dividing both sides of the equation by 10, It becomes

10x/10 = 110/10

x = 11

b) angle C = 2x - 10 = 2 × 11 - 10

Angle C = 22 - 10 = 12 degrees

Step-by-step explanation:

The margin of error is 7%. This means the 63% could either 7% too high or 7% too low. Answer choice A is the only answer choice that is within the range of percents that it could possibly be(between 56% and 70%). Answer choice B is 10% off, 3% out of the range. Answer choice C is 25% off, 18% out of the range. Answer choice D is 32% off, 24% out of the range. Hope this helps. :)

Anyone please answer me ,<br> Please solve this question
Mamont248 [21]

Answer:

67

Step-by-step explanation:

Multi-Inscribed Quadrilateral: 15

Bananas: 4

Clock: 3

Therefore, we can substitute for the last equation the values, so it would become:

3 + 4 + 4 x 15 = ?

First, we solve the multiplication according to PEMDAS.

4 x 15 = 60

Then, we can add from left to right.

3 + 4 + 60 = ?

3 + 4  = 7

7 + 60 = 67

Therefore, our answer would be 67.

Write the numerical expression for the product of 8 and the sum of 9 and 11.3. Then evaluate it.
Klio2033 [76]

Answer:

162.4

Step-by-step explanation:

To write the numerical expression for the product of 8 and the sum of 9 and 11.3 we need to follow these steps:

Sum of 9 and 11.3 is given as follows:

(9+11.3)

Now the product of 8 and the sum of 9 and 11.3 is:

8(9+11.3)

So the required expression is:

8(9+11.3)

Solving the above expression we get:

8(9+11.3)=8(20.3)=8 \times 20.3=162.4
