Find the value of X.

Mathematics
1 answer:
Kobotan [32]3 years ago
3 0

Answer:

x = 18.46

Step-by-step explanation:

Find the last angle of the triangle.

180-90-72 = 18

The cosine of an angle is equal to the ratio of the adjacent side to the hypotenuse.

cos(b) = adj/hyp

CosB=a/c rewrite to get

6/CosB (72)  = 19.41

Find the last side of the triangle using the Pythagorean theorem.

b=square root c^2 - a^2

b=square root 376.99 - 36

b= 18.46

HELP HELP MEEEEEEE Determine whether the triangles are similar. If they are write similarity statement. Explain your reasoning.
Alex_Xolod [135]

Answer:

no

Step-by-step explanation:

every triangles degrees equal 180.

78+21=99

180-99=81

the smaller triangle

21+80= 101

180-101=79

so the degrees are different

Two angles are supplementary. One angle can be represented by 2x, while the other by 3x-10. What is the value of 2x? Based on th
liubo4ka [24]
Supplementary angles = 180
2x +3x-10 = 180
5x -10 =180
5x -10 +10 =180+10
5x =190
5x/5 =190/5
x = 38
2x=76
3x-10= 3(38)-10=104

The measure of angles are 76 and 104

Factor 1 and 2. You do NOT need to show or explain steps for 1-2.
kogti [31]

Answer:

Step-by-step explanation:

x² + 9x + 18 = x² + 6x + 3x + 18

                   = x(x + 6) + 3(x + 6)

                   = (x + 3)(x + 6)

x² + 16x + 63 = x² + 9x + 7x + 63

                     = x(x + 9) + 7( x+ 9)

                     = (x + 7)(x + 9)

y² + 13y + 36 = y²+ 9y + 4y + 36

                     = y(y + 9) + 4(y + 9)

                     = (y + 4)(y + 9)

(a). Factored form of the expression (y² + 13y + 36) is (y + 4)(y + 9).

Therefore, Lyndsey's answer is wrong.

(b). Factors are (y + 4) and (y + 9).

(c). Factored form of the expression should be (y + 4)(y + 9) instead of Lindsey's answer (y + 6)(y + 6).
