Answer:

Heya mate here's the answer

let the 4th angle be x

so 75°+ 75°+75° +x= 360°

=> x= 360 - 225

=> x = 135°

therefore the 4th angle= 135°

hope this helps

Answer:

Total volume of the figure = 1067 cm³

Step-by-step explanation:

Volume of the composite figure = Volume of the rectangular prism + Volume of the square pyramid

Volume of the rectangular prism = Length × Width × Height

= 10 × 10 × 7

= 700 cm³

Volume of the square pyramid = $\frac{1}{3}(\text{Area of the base})\times (\text{height})$

= $\frac{1}{3}(\text{Side})^2$ × height

= $\frac{1}{3}(10)^2(18-7)$

= 366.67 cm³

Total volume of the composite figure = 700 + 366.67 = 1066.67 cm³

≈ 1067 cm³

May run 6 miles in 54 minutes how long will it take her to run 10 miles

djyliett [7]

Answer:

It would take her 90 minutes to run 10 miles.

Step-by-step explanation:

First you should divide 54 by 6 and you'll get 9. So it takes her 9 minutes to run 10 miles (which is physically impossible). You multiply 9 times 10 and get 90.
