Answer:

x = 4.1 cm

Step-by-step explanation:

To find x, apply pythagorean theorem, which is given as:

c² = b² + a²

Where,

c = 8.8 cm

b = ½(15.6) = 7.8 cm

a = x

Plug in the values

8.8² = 7.8² + x²

77.44 = 60.84 + x²

Subtract both sides by 60.84

77.44 - 60.84 = x²

16.6 = x²

Take the square root of both sides

√16.6 = x

x = 4.07430976

x = 4.1 cm (nearest tenth)

How do I graph quadratic equations: y=(x+2)^2-1
Fudgin [204]
Easiest way is if you have a graphing calculator, but if not. Simply plug in values for x, starting at -2 for this equation, and then find the corresponding y values. Then plot.

Fill in the blanks<br>864+2006=--------+864<br><br>5351 +(574+799)= 574+(5351+_____)​
Mama L [17]

Answer:

2006

799

Step-by-step explanation:

Given the expression:

The right hand side of the sun must be equal to the left hand side ;

Therefore ;

864+2006=--------+864

The sum of 864 and 2006 must be equal to the right hand side sum ; hence

864+2006= 2006 +864

Similarly, the left hand side and right havd side must also be equal here ;

5351 + 574 + 799 = 574 + 5351 + 799

Hence, the missing value is 799

Answer:

Step-by-step explanation:

This is a right triangle trig problem. The base of the right triangle is the distance that Donna if from the flagpole; the flagpole is the side opposite the reference angle which was given as 26, and we are looking for the height of the flagpole, h. The trig ratio that uses the side opposite over the side adjacent is the tangent ratio, specifically:

tan26=\frac{h}{123} and

123tan(26) = h so

h = 60.0 rounded to the nearest tenth. But that is only the height from her line of vision and up, not the whole height. In order to find the whole height, we have to add in her height up to her line of vision which is 5.3 feet. Therefore, the height of the flagpole is

60.0 + 5.3 = 65.3 feet.
