5^2-11 over 6(3). Evaluate the expression. A. 7. B. 2/9. C.-1/63. D. 7/9

Mathematics

atroni [7]4 years ago

The first thing you do is exponents, so you get (25-11)/6(3). After that simplify the denominator to 18. So, you get (25-11)/18. When you subtract the numerator you get 14/18. This reduces to 7/9.

So the answer is D, 7/9.

Hope this helps!

Geometry Question: BK bisects angle ABC and M angle ABK=28.3 degrees. Find M angle KBC and M angle ABC.
Nookie1986 [14]

Answer:

ABK = 28.3

Step-by-step explanation:

Given

ABK = 28.3

Required

Determine KBC

Since BK is a bisector of ABC at B,

this implies that:

ABK = KBC

Substitute 28.3 for ABK

28.3 = ABK

Reorder

ABK = 28.3

An isosceles triangle has an angle that measures 38degrees. What measures are possible for the other two angles? Choose all that
Sphinxa [80]

Answer:

  • 71° and 71°.

⠀

Step-by-step explanation:

The triangle having two sides equal along with one different side is called an isosceles triangle.

⠀

  • So, Let us assume the other sides (two equal sides) of the isosceles triangle as x. As the different side is already given in the question.

⠀

We know that,

  • The sum of all angles of a triangle is 180°

⠀

So, According to the question :

⠀

{\longrightarrow \it\qquad { \ { {  38 \: }^{ \circ}   + x + x  =  180{}^{ \circ} }}}

⠀

{\longrightarrow \it\qquad { \ { {  38 \: }^{ \circ}   + 2x   =  180{}^{ \circ} }}}

⠀

{\longrightarrow \it\qquad { \ {   2x   =  180{}^{ \circ} - {  38 \: }^{ \circ}}}}

⠀

{\longrightarrow \it\qquad { \ {   2x   =  142{}^{ \circ}  }}}

⠀

{\longrightarrow \it\qquad { \ {   x   =    \dfrac{142{}^{ \circ}}{2}   }}}

⠀

{\longrightarrow \it\qquad { \pmb {   x   =  71^{ \circ}  }}}

⠀

Therefore,

  • The measure of the two other angles of the isosceles triangle are 71° and 71°.

Please help!<br> what is it
Dmitrij [34]

Answer:

105

Step-by-step explanation:

The interior angle for R is supplementary to the 155 degree angle

(they add to 180)

180-155=25

The sum of the interior angles of a triangle is always 180

180-50-25= 105
