Prove that the angles at the base of an isosceles triangle are acute

1. Since it is an isosceles triangle, we know that the two length sides have to be the same. Therefore, the angles across from the sides are the same. They cannot be 90 degrees or above because 90+90+0 would mean we would have all the interior angles at 180 but the thing is the third angle cannot be zero. Therefore, the other two angles cannot be 90 or more. They must be acute.



Also, if it had two right angles (90 degrees) or more, it could not close to be a triangle.

Location Score Factor (100 points each) Weight A B C Convenience 0.15 89 78 84 Parking facilities 0.20 75 93 98 Display area 0.1
Olin [163]

The maximum composite score from A, B, and C is B.

The computation of the composite score for each location is shown below

The composite score for A is,

= 0.15 × 89 + .20 × 75 + 0.18 × 92 + 0.27 × 92 + 0.10 × 93 + 0.10 × 90

= 88.05

<h3>What is the composite score?</h3>

The Composite score is the average of your four test scores, rounded to the nearest whole number. Fractions less than one-half are rounded down; fractions one-half or more are rounded up.

The composite score for B is

= 0.15 × 78 + .20 × 93 + 0.18 × 90 + 0.27 × 93 + 0.10 × 97 + 0.10 × 96

= 90.91

The composite score for C is

= 0.15 × 84 + .20 × 98 + 0.18 × 87 + 0.27 × 82 + 0.10 × 84 + 0.10 × 95

= 87.90

Therefore for computing the composite score for each location we simply multiply the weight by the A location and in the same manner as A, B, and C

b. The maximum composite score from A, B, and C is B.

Help me on this question.
NISA [10]
This question involves direct proportion which has the formula (y=kx) where y and x are the values which are proportional and k is the constant of proportionality.

The constant of proportionality is basically the value that stays the same even if the x and y values change.

In this case, the constant of proportionality would be 3/7.

Answer:its 150 percent or 3/2

Step-by-step explanation:

You can get an even number 1/3 if you spin it. You can get tails 1/2 the time uf you flip it. You can also get an odd number 2/3 of the time if you spin it. If you add 1/3, 1/2, and 2/3 you get 1.5.
