The little lines inside the two angles mean they are the same.
The 3 inside angles of a triangle equal 180 degrees.
One angle is 146 , so the other two need to equal 180-146 = 34 total.
34/ 2 = 17
Both angle 1 and angle 2 are 17 degrees each.
The answer is 233
we solve the bracket first then multiplay then add
Note that
- 36=1·36;
- 36=2·18;
- 36=3·12;
- 36=4·9;
- 36=6·6.
If neither (length and width) is divide by 6, then cases 1, 2, 3 and 5 are extra, because
- 36:6=6 (is divide by 6);
- 18:6=3 (is divide by 6);
- 12:6=2 (is divide by 6);
- 6:6=1 (is divide by 6).
The only possible dimensions are: width - 4 cm and length - 9 cm.
Then the perimeter is
cm.
Answer: 26 cm.
Answer:
b
Step-by-step explanation:
Answer:
A = 24
Step-by-step explanation:
We can see that the face of the given rectangular prism shows the width 4 and the height of 6. If we cut the figure at any point along the length 20, such that the cross section is parallel to the face, the cross section, which occurs at x length, will always have the same dimensions, that are 4 and 6.
So the area of the cross section which is parallel to the face of the given rectangular prism is given by:
A = 6 × 4
A = 24
