A triangle measures 12 degrees and 40 degrees what is the measurement of the 3rd angle of the triangle
Vinvika [58]

Answer:

\boxed{ \bold{ \huge{ \boxed{ \sf{128°}}}}}

Step-by-step explanation:

Sum of angles of triangle add up to 180°

Let the third angle be x

Create an equation and solve for x

\sf{x + 12° + 40° = 180°}

\dashrightarrow{ \sf{x + 52° = 180°}}

\dashrightarrow{ \sf{x  = 180° - 52°}}

\dashrightarrow{  \boxed{\sf{x = 128°}}}

Hope I helped!

Best regards! :D

Carlos wants to put 720 of his blocks in his toy box. A small set has 10 blocks and a large set has 100 blocks. How can you writ
Natasha_Volkova [10]

Carlos can put the blocks in this three ways:

(i) 32 large blocks and 4 small blocks.

(ii) 22 large blocks and 5 small blocks.

(iii) 12 large blocks and 6 small blocks.

The total quantity of blocks equals the number of blocks stored in the sets of blocks. Based on the information given, we derive the following algebraic expression:

10\cdot m + 100\cdot n = 720, \forall\,m,n\in \mathbb{N_{O}} (1)

Where:

  • m - Quantity of small blocks.
  • n - Quantity of large blocks.

Now we can clear n in terms of m:

100\cdot n = 720 -10\cdot m

n = 7.2-0.1\cdot m (2)

From (2) we get the following combination of sets:

1) m = 12, n= 6

2) m = 22, n = 5

3) m = 32, n = 4

Carlos can put the blocks in this three ways:

(i) 32 large blocks and 4 small blocks.

(ii) 22 large blocks and 5 small blocks.

(iii) 12 large blocks and 6 small blocks.

Find all complex solutions of 11x^2-5x+2=0. If there is more than one solution separate them with commas.
sergejj [24]

Answer:

No real solutions.

Step-by-step explanation:

Let's solve your equation step-by-step.

11x2−5x+2=0

For this equation: a=11, b=-5, c=2

11x2+−5x+2=0

Step 1: Use quadratic formula with a=11, b=-5, c=2.

x=

−b±√b2−4ac

2a

x=

−(−5)±√(−5)2−4(11)(2)

2(11)

x=

5±√−63

22
