Answer:
<em>B. 30 degrees</em>
Step-by-step explanation:
Find the diagram attached
From the diagram:
Interior angles are m<3 and m<2
Exterior angle = <4
using the rule that says that the sum of interior angles is equal to the exterior angle we have:
m<2+m<3 = m<4
(4/3)x°+20 = 2x°
multiply through by 3:
4x° + 60 = 6x°
4x°-6x° = -60
-2x° = -60
x°= -60/-2
<em>x° = 30°</em>
Hence the value of x is 30 degrees
19 + X > 26
X > 7
To break your record you need more than 7 digs
Answer:
Unreduced: (4) + (5 • x) + (-9) + (4 • x)
Reduced: 9x – 5
The biggest side should be the hypotenuse in a right triangle.
In the Pythagorean theorem, side^2 + side^2 = hypotenuse^2
28^2 + 45^2 = 53^2 if these lengths create a right triangle.
Since 28^2 + 45^2 = 2809 and 53^2 = 2809, these sides do in fact form a right triangle.
Answer:
Answer:
11+ 9 = 20
Step-by-step explanation:
=> 21-9=11
21 - 9 equals to 11 is actually a wrong answer
So in order to find the subtraction problem that will help us truly know whether the equation is wrong
=> 11+ 9 = 20
OR THE SECOND EQUATION IS
=> 21 - 11 = 10
