Round your answer to the nearest hundredth. Find angle A=?
Sonja [21]

Answer:

A=48.81

Step-by-step explanation:

it is a right angle triangle find the hypotenuse c using Pythagorean theorem:

c²=a²+b²

c²=8²+7²

c=√64+49

c=10.63

sin A =opp/hyp

sin A=8/10.63

A=  48.81

another way :

tan A=opp/adj

tan A=8/7

A=48.81

You need at least 5000 points to earn a gift card from your bank. You currently have 2700 points.
steposvetlana [31]

Answer:

x + 2700 ≥ 5000 → x ≥ 2300

Step-by-step explanation:

The inequality is: x + 2700 ≥ 5000 with x being the number of points

To solve we need to subtract 2700 from both sides to get: x ≥ 2300

HELP 100 points MATH
Scrat [10]

Answer:

D. none of the above.

Step-by-step explanation:

I can't tell from the image. But, if K is in both plane IGK and P, then the answer is probably KG. However, if K is only in IGK plane, then more information is needed so none of the above.

DG is a line only in plane P and IJ is a line only in plane P so A/B are not answers.
