Since one of the angles is 90 degrees (right angle) and the other two angles are less than 90 degrees (acute angles) it is a right triangle because it cousins of right angle. Hope this helped!
I think this is a repeat question from yesterday.
f(x)=3x+1
g(x)=x^2-1
f o g (x) = f(g(x))=f(x^2-1)=3((x^2-1))+1=3x^2-3+1=3x^2-2
f o g(2)=3(2^2)-2=3(4)-2=10
Answer:
104
Step-by-step explanation:
square:8*8=64
left triangle: 1/2*8*5=20 (same for right triangle)
total area= 64+40=104
The value of x is 28 millimeters in the composite figure of two right-angled triangles lying next to each other
<h3>What is a composite figure?</h3>
A composite figure is a figure that is produced from the combination of two geometric shapes together.
The diagrammatic expression of a composite figure consists of two right-angled triangles lying next to each other can be seen in the image attached below.
For the left-side right-angled triangle, we have:
13² = h² + 5²
h² = 13² - 5²
h = √(169-25)
h = 12
Recall from the diagram that:
h² = pq
∴
12² = 5x
x = 144/5
x ≅ 28 millimeters
