Answer:
58 degrees
Step-by-step explanation:
In a rectangle, the two diagonals form four isosceles triangles. This means triangle EBC is isosceles. In an isosceles triangle, the two base angles are the same. So, angles EBC and BCE are both 61. Now, in a triangle, the three angles add up to 180. So, 61+61=122, and to find angle CEB you need to subtract 180-122. 180-122=58 degrees.
Answer: 8^4
Step-by-step explanation:
2 hours is equivalence of 120 minutes
If he reads 100 pages in 120 minutes,
the he reads (48 * 100) / 120 pages in 48 minutes = 4800/120 pages = 40 pages
He reads 40 pages in 48 minutes.
15 yd
as area of traingle = 1/2 × base × height
and base = 10 yd
height = 3 yd
therefore.
area = 1/2 × 10 × 3
=10×3÷2
= 15 yd square
