Answer:
∠ VWU = 48°
Step-by-step explanation:
Since VW and VU are congruent then the triangle is isosceles with 2 base angles being congruent , that is
∠ VWU = ∠ VUW , then
∠ VWU = 
= 
= 48°
Answer:
x=-4 y=5
Step-by-step explanation:
3×(16-4y)+4y=8
48-12y+4y=8
-8y=-40
y=5
x=16-4×5
x=-4
Options A,B and D. The correction about the area of the triangle are
- The apothem can be found using the Pythagorean theorem.
- The apothem can be found using the tangent ratio.
- The length of the apothem is approximately 2.5 cm.
<h3>How to solve for the length of the Apothem using the Pythagoras theorem</h3>
Firstly this is an equilateral triangle
3 of the sides have the length of 8.7cm
b = half of 8.7
= 4.35cm
To get A we have
a² + b² = c²
a² + 4.35² = 5²
When we solve this out we would have
a² = 25 - 18.9225
a ≈ 2.5 cm.
Hence we have proved that the first option is correct.
<u>For B,</u>
In an equilateral triangles, each of the angles = 60 degrees
60/2 = 30 is the angle that is made from the base
<h3>using tangent ratios </h3>
a / 4.35 = tan 30
then a = 4.35 tan 30
This would also give us an approximate of 2.5
For D
The calculations we have done based on the statements in A and B shows that D is correct as 2.5.
