Answer:
The math test had 10 equation questions and 16 vocabulary questions.
Step-by-step explanation:
Given:
Total number of questions in the math test = 26
Total marks of the math test = 100
Points for one equation question = 2
Points for one vocabulary question = 5
To Find:
The number of equation question and vocabulary question = ?
Solution:
Let the number of equation question be x and the number of vocabulary question be y
Then
x+y = 26--------------------------(1)
----------------------(2)
From equation (1), we get
x = 26-y-----------------------------(3)
Substituting (3) in (2), we get
Now solving the above equation
y=16
Substituting y =16 in eq(3),
x = 26-16
x= 10
B = 3h . . . . . . . .given by the problem statement
A = (1/2)bh . . . . formula for the area of a triangle
486 cm² = (1/2)*(3h)*h . . . substitute given information
(2/3)*486 cm² = h² . . . . . .multiply by 2/3
√324 cm = h . . . . . . . . . . . . . .take the square root
The height is 18 cm.
The base is 3*18 = 54 cm.
Answer:
Construct the angle bisector of angle Y
Step-by-step explanation:
-An inscribed circle is defined as the largest circle that can be drawn within the boundaries of a plane figure.
-The first step in constructing an inscribed circle is to bisect any two angles of the plane figure, triangle in this case, as there intersection point will form the circle's center.
=>Hence, the first step is Construct the angle bisector of angle Y or Z or X( whichever you decide on).

Step-by-step explanation:
Answer:
20.5 cm
Step-by-step explanation:
I just used Pythagorean theorem in which c^2=a^2+b^2
so this is c^2= 225 + 196 and then you get c^2= 421 and finally you get the square root of 421 so this way you finally get 20.5 cm
