Answer:
13 , 35
Step-by-step explanation:
Let's call one of the number x and the other y
x + y = 47
x - y = 21 and x = 21 + y if we use this expression in the first equation instead of x we can find the value of y
x + y = 47 ➡ y + y + 21 = 47 add like terms
2y +21 = 47
2y = 47 - 21
2y = 26
y = 13 the value of first number is 13
x + y = 47 we know y is 13 so we can replace it
x + 13 = 47
x = 35
Answer:
The three given points are the vertices of a right triangle.
Step-by-step explanation:
Given :
- Base = 20 cm and 14 cm.
- Height = 5 cm.
To find :
Solution :
We know,
Now, Substituting the values :
Therefore,
- <u>The area of the trapezoid is 85 cm²</u> .
"An angle that forms a linear pair with one of the interior angle the triangle" is the best definition of an exterior angle of a triangle.
<u>Option: C</u>
<u>Explanation:</u>
When to the sum of the inward angles opposite outer angle of a triangle the sum of the inward angles opposite is equivalent thus understood as exterior angle of a triangle.
The Triangle outer angle theorem for more about is if at each vertex the equivalent angle is drawn, the outer angles always add up to 360°. In reality, this is valid for any convex polygon, not just triangles.
In the most easiest pattern , since any angle of triangle equivalent is 60′, the outer angle would be 120′. Therefore all exterior angles sum is:
120 + 120 + 120 = 360°.
The answer is 13.
A cuboid has 12 edges. and a cone has one (the base).
The curved part is not counted as an edge.
Hope this helps!
