Please solve this equation
tangare [24]

Answer:

∠2 = 41°

Step-by-step explanation:

This is because, all three interior angles in a triangle will have a sum of 180 degrees.

So given that we have two angles, 90 degrees(right angle) and 49 degrees, we can replace angle 2 as our unknown value(a variable) and make it equal to 180 degrees then solve for x;

49 + 90 + x = 180

139 + x = 180

-139        -139

x = 41°, ∠2 = 41°

andreyandreev [35.5K]

Answer:

115\ white\ rose\ bushes

Step-by-step explanation:

Let

x------> the number of pink roses bushes

y----> the number of white rose bushes

we know that

\frac{x}{y} =\frac{12}{15}

y=\frac{15}{12}x -----> equation A

x=92

substitute the value of x in the equation A

y=\frac{15}{12}(92)=115\ white\ rose\ bushes

Plastic Knives are sold in packs of 18 for 45p. Plastic Forks are sold in packs of 15 for 41p. Jace wants to buy the same number
Flauer [41]

Answer:

430p

Step-by-step explanation:

For this, we'll find the least common multiple for 15 and 18.

=> The least common multiple for 15 and 18 is 90

<u><em>Plastic Knives:</em></u>

Jace will buy 90 knives.  

=> Packets = 90/18 = 5 Packets

Money for 5 Packets = 5 * 45

=> 225p

<u><em>Plastic Forks:</em></u>

Jace will buy 90 forks also.

=> Packets = 90/15 = 6 Packets

Money fro 6 packets = 6 * 41

=> 205p

<u><em>Least Amount of Money Jace will spend</em></u> = 225p+205p

=> 430p
