Bisect the marked angle on the diagram below.

Jibu: $\boxed{\text{612}}$

2. Workout: $\frac{2}{5} + \frac{1}{4}$

Jibu: $\boxed{\text{}\frac{13}{20}\text{}}$

3. Solve: $8p - 4 = 20$

Jibu: $\boxed{\text{3}}$

4. The total distance around is 56m. If the ratio of width is 4:3 respectively length.
Tuchukulie umbo ni mstatili. "Total distance around" inamaanisha mzingo (perimeter).

Mzingo $P = 2(upana + urefu)$.
Tunapewa $P = 56$ m.
Uwiano wa upana kwa urefu ni $upana : urefu = 4 : 3$.
Hivyo, tunaweza kuandika $upana = 4x$ na $urefu = 3x$ kwa thamani fulani ya $x$.

Upana $= 4x = 4 \times 4 = 16$ m.
Urefu $= 3x = 3 \times 4 = 12$ m.
Jibu: Upana ni 16 m na urefu ni 12 m.

5. Change 140 minutes to hours.

Gawanya dakika 140 kwa 60.

Jibu: $\boxed{\text{2}\frac{1}{3} \text{ masaa}}$

6. Find the value of $x$ 2
Swali hili halijakamilika. Tafadhali toa mlinganyo kamili au usemi ili niweze kutafuta thamani ya $x$.

7. Bisect the marked angle on the diagram below.
Ili kugawanya pembe $\angle ABC$ mara mbili (bisect), fuata hatua hizi za ujenzi:

Chora tao linalokata mikono yote miwili ya pembe (BA na BC) kwenye pointi mbili tofauti, tuseme D na E.

Weka alama ya makutano ya matao haya kama F.

Mstari huu BF ndio kigawanyaji cha pembe (angle bisector) ya $\angle ABC$.

8. Prime factorise 28 and write your answer in set notation.

Anza kugawanya 28 kwa namba kuu ndogo zaidi.

Hivyo, vigawo vikuu vya 28 ni 2, 2, na 7.

Jibu: $\boxed{\text{}\{2, 7\}\text{}}$

9. A Cylindrical ti top and bottom
Swali hili halijakamilika. Tafadhali toa maelezo kamili ya swali kuhusu silinda.
