Answer:
A
Step-by-step explanation:
When you distribute values, 'a' while be multiplied by everything. since there is a plus sign in front of the 'b' then that will not be distributed. so an 'ab' will add the an 'ac' but an 'ad' is still going to subtract away from the equation.
Answer:
AC = BC = 5
AB = 5√2
∠A = ∠B = 45
∠A = 90
Step-by-step explanation:
AC = 5 ( Reason : 5 squares are present in between A and C )
Similarly,
BC = 5
<u>By Pythagoras theorem</u>,
(AB)² = (AC)² + (BC)²
= 5² + 5²
= 2 * 5²
(AB)² = 2 * 5²
AB = 5√2
Since, sides AC and BC are equal,
∠A = ∠B = 45
Since, AC is perpendicular to BC,
∠A = 90
Answer:
It will take about 15-20 Minutes to catch up to that bus.
Step-by-step explanation:
65+ 20= 85 so its a tad bit over but it works.
Answer:
9 sides
Step-by-step explanation:
exterior angle + interior angle = 180° , so
exterior angle + 140° = 180° ( subtract 140° from both sides )
exterior angle = 40°
The sum of the exterior angles of a polygon = 360°
Dividing sum by the measure of 1 exterior angles gives number of sides
number of sides =
= 9
Solution:
<u>Note that:</u>
- Area of trapezoid = Area of triangle + Area of square = 575 m²
- Area of triangle = 32.5 m²
- Area of square = s²
<u>Finding the area of the square:</u>
- 32.5 + Area of square = 575 m²
- => Area of square = 575 - 32.5
- => Area of square = 542.5
- => s² = 542.5
- => s = √542.5 ≈ 23.29
The length of the square is 23.29 meters.
