Answer:

34°

Step-by-step explanation:

The measure of vertical angles formed by two chords is equal to one half the sum the measures of the arcs.

In other words, x is the average:

x = (23° + 45°) / 2

x = 34°

To find the area, we need the height of the triangle first. We already have the base.

Let's find the height (BA)
tan = opposite / adjacent

tan 35 = BA / 12
BA = 12 * tan35
BA = 12 * 0.7002079283708176
BA = 8.402

Area of the triangle = 12*BA/2 = 6*BA = 50.412 square units

Your answer should be a polynomial in standard form. ( − 2 h + 9 ) ( 9 h − 2 ) = (−2h+9)(9h−2)=

AleksandrR [38]

Answer:

$-18\cdot h^{2} + 85\cdot h - 18$

Step-by-step explanation:

The polynomial in standard form is:

$(-2\cdot h + 9) \cdot (9\cdot h - 2)$

$-18\cdot h^{2} + 81\cdot h +4 \cdot h - 18$

$-18\cdot h^{2} + 85\cdot h - 18$

kvv77 [185]

Answer:

24 bracelets can be made from given beads.

● Explanation -To make similar bracelets using all the beads, we have to find the highest common factor of no of beads.Now, Factors of 72 => 1, 2, 3, 4, 6, 8 , 9, 12, 18, 24, 36, 72Factors of 192 => 1, 2, 3, 4, 6, 8, 12, 16, 24, 32, 48, 64, 96, 192Factors of 120 => 1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 20, 24, 30, 40, 60, 120HCF => 24Observing this data, HCF of 72, 192 & 120 will be 24.Therefore, total 24 bracelets can be made from given beads.* Each bracelet will have 3 red, 8 blue and 5 white beads.
