Answer:
Step-by-step explanation:
By triangle sum theorem,
Sum of interior angles of a triangle is 180°.
Therefore, measure of third angle in the larger triangle = 180° - (35° + 120°) = 25°
Similarly, measure of third angle in the smaller triangle = 180° - (25° + 120°)
= 35°
Since, measure of interior angles of larger triangle is equal to the measure of smaller triangle,
Both the triangles will be similar by AA property of similarity.
Answer:
Step-by-step explanation:
<u>Let the cost of a sheet be s and cost of a blanket be b</u>
<u>From the first equation we get:</u>
<u>Substitute in the second equation</u>
- s + 4*(41 - 2s) = 80
- s + 164 - 8s = 80
- 7s = 84
- s = 12
<u>Then</u>
Answer:
285
Step-by-step explanation:
9 = 7 + 2¹
13 = 9 + 2²
29 = 13 + 2⁴
285 = 29 + 2⁸
Rectangular book
two 8 1/2 sides
two 9 1/4 sides
8 1/2*2=17
9 1/4*2=18 1/2
17+18 1/2= 35 1/2
The perimeter of the textbook is 35 1/2 inches or 35.5 inches.
Hope this helps :)
