Answer:
72
Step-by-step explanation:
The area (A) of a rhombus is calculated as
A = 
× d₁ × d₂ (d₁ and d₂ are the diagonals )
The diagonals bisect each other at right angles
d₁ = 2 × 6 = 12
Use the tangent ration in the upper left right triangle and the exact value
tan60° =
tan60° = 
= 
= ( multiply both sides by 6 )
opp = 6 , then
d₂ = 2 × 6 = 12
Thus
A = × 12 × 12 = 6 × 12 = 72
Given:
Principal = <span>£100
Interest rate = 6%
Interest = </span><span>£12
Simple Interest is computed by multiplying the principal by its interest rate and term
Interest = Principal * rate * term
12 = 100 * 0.06 * term
12 = 6 * term
12/6 = term
2 = term
It will take 2 years for </span>£100 to earn <span>£12 at 6%</span>
Answer:
The vertex angle is 94 degrees
Step-by-step explanation:
Let the vertex angle be x
Mathematically, the base angles of an isosceles triangle are the same
So if one of the base angles is 43 degrees, then the other base angle would be 43 degrees too
Mathematically, the sum of angles in a triangle is 180 degrees
Thus;
43 + 43 + x = 180
x = 180-86
x = 94 degrees
Congruent triangles are triangles that have the same size and shape. In particular, corresponding angles <span>have the same measure, and corresponding sides have the same length. </span>converse. close window.Converse means<span> the "if" and "then" parts of a sentence are switched.</span>
