- Temperature drops
If the temperature of a city drops 2° every day and increases by 3° every five days, how long does it take to drop to -15° from temperature +5°? - Classroom 81621
On a classroom clock, the large (minute) hand on the clock will travel through an angle of 120 degrees in some time. What angle does the small (hour) hand pass in this time? - Equal temperature
We measured the temperatures of the two cities at the same time. The temperature in town A was 60 degrees And rose at a constant rate of 2 degrees per hour. The temperature in city B was 40° and rose at a constant rate of 10° per hour. Find the time in ho - Rubberized 33173
Jaro had 4 angles written in his notebook, the sum of which was a right angle. The little sister rubberized one corner of it. Determine its size if the remaining angles remain written in the notebook: 12°34, 34°56, 56°9.
- Temperature variations
Today's temperature was 80 degrees, and then the temperature dropped 10 degrees. Then it dropped 15 degrees again; the next day, the temperature went up 2 degrees. What would the temperature be? - RWY
Calculate the opposite direction of the runway 13. Runways are named by a number between 01 and 36, which is generally one-tenth of the azimuth of the runway's heading in degrees: a runway numbered 09 points east (90°), runway 18 is south (180°), runway 2 - Triangle P2
Can a triangle have two right angles? - Remaining 25441
An isosceles triangle has the size of the angles at the base alpha = beta = 34 degrees 34 minutes. Calculate the magnitude of the angle at the remaining vertex of the triangle in degrees and minutes. - Main/central vertex
ABC is an isosceles triangle with base BC and central vertex A. The angle at vertex A is 18°. What will be the size of the angle at vertex B?
- Gamma angle
Find the magnitude of the gamma angle in triangle ABC if: α = 38° 56' and β = 47° 54'. - Calculate 82878
Calculate in degrees the size of the acute angle made by the hands of the clock at half past six. - The two
The two angles of a triangle are 78° and 82°. So, what is the measure of the remaining third angle? - Calculate 6678
You know the size of the two interior angles of the triangle alpha = 40 ° beta = 60 °. Calculate the size of the third interior angle. - Angles
The triangle is one outer angle 158°54' and one internal angle 148°. Calculate the other interior angles of a triangle.
- Isosceles 65784
An isosceles triangle has an angle of 78°20' at the base. Calculate the size of the angle between the arms. - It is rectangular?
The size of two of the angles in a triangle is α=110°, β=40°. Is it a right triangle? - Triangle radians
The size of two internal angles of a triangle ABC is α=6/18π and β=7/18π. Calculate the size of the third angle. - Triangle
By calculation, determine if it is possible to construct a triangle with sides 10 21 19. - 3-bracket 3
Two angles in a triangle are 90° and 60°. Has the triangle at least two equal sides?
