Step-by-step explanation:
TRIANGLE 1
c = 2√5
= 2 × √5
= √4 × √5
= √20
a = 2
b = ?
b² = c² - a²
= √20² - 2²
= 20² - 4
= 400 - 4
= 396
b = √396
= √36 × √11
= 6 × √11
= 6 √11
TRIAGLE 2
a = 12
b = 6√11
= √396
c = ?
c² = a² + b²
= 12² + √396
= 144 + √396²
= 144 + 396
c = √540
= √36 × √15
= 6 × √15
= 6 √15

Step-by-step explanation:TO EZ I BIG BRAIN
To answer this first we need to find out how much Tiffany earns per hour and then we will multiply. lets do it:-
77.28 ÷ 4 = 19.32
$19.32 per hr
CHECK OUR WORK:-
19.32 × 4 = 77.28
we were RIGHT!!
Now lets see how much she earns in 15 hrs.
19.32 × 15 = 289.8
Tiffany earns $289.8 to work for 15 hrs.
CHECK OUR WORK:-
289.8 ÷ 15 = 19.32
we were RIGHT!!
So, Tiffany earns $289.8 to work for 15 hrs.
Hope I helped ya!!
