They give us a few of the rare angles we can get exact answers for and then they ask for an approximation. Amateurs.
In the 30/60/90 triangle the sides are in ratio 1:√3:2. So for the big side 22 the altitude h=11 and the part of the base to the right of the right angle is 11√3.
In the 45/45/90 triangle the sides are in ratio 1:1:√2 so the altitude h=x/√2 and the base to the left of the right angle is also h. So
x = h√2 = 11√2
y = 11√3 + 11
I hate ruining a nice exact answer with an approximation but they asked:
Answer: x=15.56 y=30.05
Answer:
Step-by-step explanation:
a). By applying Pythagoras theorem in right triangle ABC,
AC² = AB² + BC²
20² = 16² + BC²
BC =
= 12
Therefore, another leg of the triangular base = 12 cm
Area of the triangular base ABC =
=
= 96 cm²
Volume of a triangular prism = Area of the triangular base × height
960 = 96 × b
b = 10 cm
b). Area of the triangle ABC = 96 cm²
Answer:
-2
Assumption:
Find the value of x such that .
Step-by-step explanation:
Combine like terms:
This is not too bad too factor on the left hand side since 2(2)=4 and 2+2=4.
So we need to solve:
Subtract 2 on both sides:
Let's check:
0 was the desired output of .
Answer:
21³
it's the answer coz in division power is subtracted
mark me brainliest
Answer:
1.85
Step-by-step explanation:
So, s (sketchbook) is a+1.90.
8a+ 3(a+1.90)=26.05
8a+3a+5.7=26.05
11a=20.35
a=1.85
Check:
8x1.85=14.8
s=11.25
