How to calculate angle BCE?

Mathematics
1 answer:
Olenka [21]3 years ago
5 0

Answer:

75.3 degrees ( to nearest tenth).

Step-by-step explanation:

If we take a section  through the plane BCHE we get a rectangle.

BC = 2 cm and BE  = √(7^2 + 3^2). ( By the pythagoras theorem).

tan < BCE = √(7^2 + 3^2) / 2.

So the m < BCE = 75.3 degrees.

Mazyrski [523]

Answer:

3213 cm

Step-by-step explanation:

First draw the frame around the triangle. The circular edges added together give you 360 degrees. Use pi*r^2 to get 4pi which is around 12.56. 100cm=m. 2*500+2*400*2*700=3200.

3200+ 13 = 3213

Help find x. I believe it’s 13
aksik [14]

Answer:

m∠RST = 155°

m∠RSU = 102°

Step-by-step explanation:

m∠RST  = m∠RSU + m∠UST

12x - 1    = 9x - 15 + 53

12x - 9x = 1- 15 + 53

      3x   = 39

        x   = 39/3

         x = 13°

m∠RST  = (12x -1)° = (12 * 13 - 1)° =   (156 - 1 )° = 155°

m∠RSU = (9x -15)° = (9 * 13 - 15)° = ( 117 - 15)° = 102°

(150 - 30) divided by 15 = $8

Only $8 maximum can be spent on each family member
