Answer:
(a) x = 22
(b) 46°
(c) 44°
(d) 180°
Step-by-step explanation:
Because the sum of the interior angles of a triangle is 180°, we know that the sum of the acute angles in a right triangle is 90°.
<h3>(a) </h3>
The sum of the marked acute angles is 90°.
2x +(3x -20) = 90
5x = 110 . . . . . . . . . . add 20, collect terms
x = 22 . . . . . . . . . divide by 5
__
<h3>(b) </h3>
∠CBA = (3x -20)° = (3·22 -20)° = 46°
__
<h3>(c)</h3>
∠CAB = 2x° = 2(22)° = 44°
__
<h3>(d)</h3>
The sum of a triangle's interior angles is 180°.
Step-by-step explanation:
is that all the question?
Median = 75 because that is where the middle line of the box is.
First quartile = 70 because that is what the left edge of the box represents.
Third quartile = 85 because the right edge of the box indicates that.
Maximum = 100 because at the far right is the maximum data point of your data set.
The middle 50% of that data is between 70 and 85 because those are the values the box covers. It goes from the first quartile, 70, and stretches all the way to the third quartile 85.
Which of the lists is in order from smallest to largest? 1,330; 3,130; 3,310; 3,031 3,130; 3,031; 3,310; 1,330 1,330; 3,310; 3,0
lesantik [10]
Its the 4th because, 1,330 is the smallest then 3,031 is the second then, 3,130 is the third then fourth is 3,310
If you are asking for an equation for this statement, it would be y = x + 5
