Answer:
Whole number
Step-by-step explanation:
That's only because it is just 1 number that is gonna be there and i did some research too
Answer:
D
Step-by-step explanation:
The lines are parallel, this means that they will never meet.
Answer:
<u>Option B. sin(s) = cos(u)</u>
Step-by-step explanation:
The rest of the question is the attached figure.
Complementary angles - two angles that add to 90 degrees.
The sine of one of them will be equal to the cosine of other angle.
For the attached figure:
The set all complementary angles are:
- angle s and angle t
- angle u and angle v
- angle s and angle u
- angle t and angle v
We will check the options:
A. sin(t) = sin(u) ⇒(<u>wrong</u>) because t and u are not complementary angles
B. sin(s) = cos(u) ⇒ (<u>True</u>) ⇒ s and u are complementary angles and sine of one of them will be equal to the cosine of other angle.
C. cos(s) = sin(v) ⇒(<u>wrong</u>) because t and u are not complementary angles
D. cos(t) = cos(v) ⇒(<u>wrong</u>) because t and v are complementary angles but sine of one of them should be equal to the cosine of other angle.
<u>The answer is option B. sin(s) = cos(u)</u>
Answer:
figure 1 - 10.5 unit^2
figure 2 - 12 unit^2
Step-by-step explanation:
<u>figure 1</u>
1. find the area of the rectangle
<em>3*2 = 6 unit^2</em>
2. find the area of the triangle
<em>(3*3)/2 = 4.5 unit^2</em>
3. add the area of the rectangle and the area of the triangle together. The sum would be the area of the trapezoid.
<em>6 + 4.5 = </em><u><em>10.5 unit^2</em></u>
<u>figure 2</u>
1. find the area of the rectangle
<em>2*4 = 8 unit^2</em>
2. find the area of both triangles
<em>(1*4)/2 = 2 unit^2</em>
3. add the area of the rectangle and the area of both triangles together. The sum would be the area of the trapezoid.
<em>8 + 2 + 2 = </em><u><em>12 unit^2</em></u>
