For this composite question you will need to divide the shape into two different shapes. The large rectangle is going to be 60 in square because of base times height and then you would need to find the square which would be 4 times 4 cause of base times height but because it’s a triable you divide by 3 so 16/2 would be 8 than you would add both shapes and get 68 in squared. Hope that helps!
Answer:
A) ERROR
B) ∠C = 26°
Step-by-step explanation:
Houston, We have a problem!!! too much information
If we had a legit triangle, the law of sines would hold
19/sin138 = 8/sin20
28.395 = 23.390
as this is NOT an equality, the triangle does not exist as described.
IF it did, we'd get different results depending on which set we used
∠F = 180 - 138 - 20 = 22°
Law of sines
19/sin138 = DE/sin22 ⇒ DE = 19sin22/sin138 = <u>10.63697...</u>
or
8/sin20 = DE/sin22 ⇒ DE = 8sin22/sin20 = <u>8.762211...</u>
If we attempt to use Law of cosines
DE² = 19² + 8² - 2(19)(8)cos22 = <u>11.9639...</u>
so really none is correct because we attempt to use trig calculations to a non-triangle.
12) AC² = 15² + 19² - 2(15)(19)cos120
AC = 29.51270...
29.51270 / sin120 = 15/sinC
C = arcsin(15sin120/29.51270) = 26.1142... <u>26°</u>
<h2>question :</h2>
40. which of the following equation graphs as a vertical parallel to the y-axis?
41. if ΔABC = ΔFGH, then which of the following statements is not necessarily true?
<h2>my answer :</h2>
40. the meaning of "vertical parallel to the y-axis" is a line that is perpendicular to the x-axis
then the equation that can be written parallel to the line y is x = a, a is the distance from point 0.
(*the second choice is correct)
41. if ΔABC = ΔFGH, it can be said that the second triangle of the shape is congruous (*in the picture)
(*the second choice is correct)
The area of steel before cutting:
Area =
cm²
= 
Hence, Area=
Area of steel after cutting out the 11*6 inside dimensions.
As the area should be close to 28 cm square, so equation becomes:
or 
Now for the answer, kindly see the image attached. It gives x=0.76
Hence, the answer is 0.76 cm.
