Answer:

93 m

Step-by-step explanation:

We solve this above question using the Trigonometric function of Tangent

tan θ = Opposite/Adjacent

Opposite = Height of the tree = ?? = x

Adjacent = Distance from the base of the tree = 78m

θ = 50°

Hence:

tan 50 = x/78

Cross Multiply

x = tan 50 × 78

x = 92.956780222m

Approximately = 93 m

Therefore, the tree is 93 meters tall

The sum of two consecutive integers is 77. Find the integers.
SIZIF [17.4K]

Answer:

38 and 39

Step-by-step explanation:

Since the two integers are consecutive, then one is one larger than the other. Therefore, lets call them x and x+1. We can now set up the following equation:

x+(x+1)=77

2x+1=77

2x=76

x=38

x+1=39

Hope this helps!

An abstract sculpture in the form of a triangle has a base 21 meters and a height of 12 meters. Find the are of the triangle.
charle [14.2K]
The area of a triangle could be determined using the following formula
\boxed{a= \frac{1}{2} \times b \times h}

plug in the numbers
a =  \frac{1}{2} \times 21 \times 12
a =  \frac{1}{2} \times 252
a= \frac{252}{2}
a = 126

The area of the triangle is 126 square meters

The test scores of 40 students are listed below. Find P85.
SIZIF [17.4K]

Answer:

Option A (89).

Step-by-step explanation:

Percentile is a statistic in which the an element at a certain percentage position is determined. To calculate the percentiles accurately, it is important that the data is present in the ascending order. Percentile is an important concept in data analysis. Interestingly, 50th percentile is the median of the data. The difference between the 75th and the 25th percentile is the interquartile range. To find the 85th percentile of the data, calculate 85% of 40, which is the number of elements in the data set. 40 * 85/100 = 34. The number on the 34th position is the 85th percentile of the data. It can be observed that 89 is on the 34th position. Therefore, Option A is the answer!!!

Artists such as Al Held, Bridget Riley etc are known for their abstract artwork or geometric artwork. Riley is famous for her optical artwork.

This art form is present among many cultures throughout the history both as decorative motifs and as art pieces themselves. Like in Islamic art, this art depicts religious figures. The optical art gives the viewer the impression of movement, hidden images, flashing and vibrating patterns. Basically it gives a disorienting effect.

Besides optical art, other abstract art forms are also famous. These imbibe a strong imagination and a sense of creativity in its viewers. This art form puts different colors, shapes, and textures together to create a finished piece that represents something in particular.

Yes, I appreciate this kind of art form because these forms are genuine and helps us understand the art patterns. Unlike the traditional form, these forms explore the relationships of forms/shapes and colors. Moreover, art always reflects culture. Therefore, abstract art is important because it is reflecting a culture that has been moving since last 2000 years.
