Diagonals of rhombus are perpendicular
area is (1/2)*d1 * d2 where d1 and d2 are the diagonal lengths
draw the diagonals on your rhombus and you will see a 30-60-90 triangle and then figure
sides will be 6 , 6√3 . 12
so d1 is 2*6 = 12
and d2 is 2*6√3 = 12√3
and area = (1/2)*12*12√3
= 72√3 square cm.
Answer:
6040
Step-by-step explanation:
140x31=4340
Add 1700
=6040
If the triangle is an equilateral triangle the angles should be all 60 as (60+60+60=180) if that’s true then a congruent line from the triangle would form a 60 degree angle.
so x=60°
Answer:
GCF = 3
Step-by-step explanation:
Express the numbers as a product of their primes.
42 = 2 × 3 + 7
30 = 2 × 3 × 5
45 = 3 × 3 × 5
Identify the prime factors common to all 3 numbers.
common prime factor = 3 , thus
GCF = 3
Answer:
x=14
Step-by-step explanation:
8x-9+6x-7 = 180 (being adjacent angles)
14x-16 = 180
14x = 180+16
14x =196
x = 196/14
x =14
