Answer:
94
Step-by-step explanation:
the sum of the angles in a triangle add up to equal 180
180-73-13=94
X y
4 650
7 575
11 475
there ya go ^^
The solution is D.
By plugging the x value, 5, into the equation:
6*5=30
30+1=31
y=31
the x value is 5 and the y value is 31
(5, 31)
hope that helps!
We are asked to find the principal value of
cos ⁻¹ (0.69)
which is just the least positive angle
cos ⁻¹ (0.69) = 46.37°
Other values of
cos ⁻¹ (0.69) is
46.37° - 180° n
where n is a whole number
Answer:
<h2>
1,190cm²</h2>
Step-by-step explanation:
The Area of a triangle is expressed as 1/2 * base * height. If uma is planning to decorate a blanket with a triangular shape that has a base of 5 centimetres and a height of 7 centimetres, area of the blanket will be expressed as shown;
Area of the blanget = 1/2 * 7 * 5
Area of a blanket = 35/2 = 17.5cm²
If she plans to cut out 68 triangles with these dimensions, the total area will be total number of triangles * area of one triangle i.e 68 * 17.5 = 1,190cm²
