A right triangle has a perpendicular corner in it. This means that one of its angle has a measure of 90 degrees. The sum of all angles in the triangle is 180. To determine the acute angle, or more importantly, the last missing angle, it would be,
180 = 90 + 63.7 + x
x = 180 - 90 - 63.7
x = 26.3 degrees
This is an acute angle because it is less than 90. So, the answer is 26.3 degrees.
Answer:
Step-by-step explanation:
y=-3x²-4x+7...(*)
3x+2y=18...(**)
use (*) put the value of y in (**) :
3x +2(-3x²-4x+7)=18
3x-6x²-8x +14 -18 = 0
-6x²-5x- 4 = 0
6x²+5x+4 = 0
delta = b² - 4ac a = 6 b=5 c =4
delta = 5² - 4(6)(4)= 25 -96= -71 negatif
so no reals solution
The first two are true and the last one is false
Answer:
46.3cm
Step-by-step explanation:
- perimeter is length around shape
- 25/2 multiply by 2 becoz it's got two equal sides
- 32/3 multiply by two for the other equal sides
- add answers together to give you
- 46.3cm
Answer/Step-by-step explanation:
Before we draw a line plot for this data we first need to put then from least to greatest. As well as how many number are each.
<em>Given the following data:</em>
<em>5 1/2</em>
<em> 5 3/4</em>
<em>5 3/4</em>
<em>5 7/8</em>
<em>5 7/8</em>
<em>6</em>
<em>6 1/8</em>
<em>6 1/8 </em>
<em>6 1/8</em>
<em>6 1/4</em>
<em>6 3/8</em>
<em>We can see that we have:</em>
<em>5 1/2 {1}</em>
<em> 5 3/4 {2}</em>
<em>5 7/8 {2}</em>
<em>6 {1}</em>
<em>6 1/8{3}</em>
<em>6 1/4 {1}</em>
<em>6 3/8 {1}</em>
<em>Now put the following from least to greatest:</em>
<em>5 1/2 {1}</em>
<em>5 3/4 {2}</em>
<em>5 7/8 {2}</em>
<em>6 {1}</em>
<em>6 1/8{3} </em>
<em>6 1/4 {1}</em>
<em>6 3/8{1}</em>
<em>We can see that they already in order thus, let put it on a line plot from least to greatest. </em>
