How many triangles can be made if one angle is 95° and another angle is obtuse?
Elenna [48]
D. None. Say the obtuse angle is 100 degrees. Since the sum of all angles in a triangle cannot be bigger than 180, it's not possible because 195 (100+95) is greater than 180 degrees. Hope this helps.

There is a total of 270 men, women and children on a train.
ryzh [129]

Because the ratio of women to children is 10:1, double the ratio of men to women so the women are both 10:

Men to women becomes 8:10

Now total the 3 ratios: 8 for men, 10, for women and 9 for children:

8 + 10 + 9 = 27

Divide total people by that number:

270/27 = 10

Multiply 10 by each ratio:

Men = 8 * 10 = 80

Women = 10 * 10 = 100

Children = 9 *10 = 90



There is 80 men.

Quadrilateral ABCD is given, the interior angle at vertex B is 97 degrees and the exterior angle at vertex A is 88 degrees. Line
Citrus2011 [14]

Answer:

angle 1 = 83°

angle 2 = 88°

Step-by-step explanation:

angle 1 and angle on vertex B are

pair of co interior angles ( whose sum = 180° )

so, angle 1 + angle B = 180°

angle 1 = 180° - angle B

angle 1 = 180° - 97° = 83°

hence, angle 1 = 83°

but, angle 2 and exterior of vertex A forms alternate interior angle pair ,

so , angle 2 = angle A = 88°

i hope you got it ....

(SAT Prep) What is the sum of lengths of the two diagonals in a rectangle 5 by 12?
Sonja [21]

Answer:

Step-by-step explanation:

To find the length of the diagonal, use Pythagorean theorem.

(diagonal)² = (length)² +(width)²

                  = 12² + 5²      

                  = 144+ 25

                 = 169

diagonal = √ 169 = 13 units

Sum of lengths of two diagonals = 13 + 13 = 26 units

In rectangle, diagonals are of equal length.
